MGI Phenotype |
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a member of the tumor necrosis factor receptor superfamily. The major ligands of this receptor include lymphotoxin alpha/beta and tumor necrosis factor ligand superfamily member 14. The encoded protein plays a role in signalling during the development of lymphoid and other organs, lipid metabolism, immune response, and programmed cell death. Activity of this receptor has also been linked to carcinogenesis. Alternatively spliced transcript variants encoding multiple isoforms have been observed. [provided by RefSeq, Aug 2012] PHENOTYPE: Homozygotes for a targeted null mutation lack Peyer's patches, colon-associated lymphoid tissues, and lymph nodes. Mutants also exhibit severely reduced numbers of NK cells and increased susceptibility to Theiler's murine encephalomyelitis virus. [provided by MGI curators]

Phenotypic Description |
The marine_blue phenotype was identified among N-ethyl-N-nitrosourea (ENU)-mutagenized G3 mice of the pedigree R5859, some of which showed increased B to T cell ratios (Figure 1), increased frequencies of B cells (Figure 2) and B1 cells (Figure 3) with concomitant reduced frequencies of CD8+ T cells (Figure 4), CD44+ T cells (Figure 5), CD44+ CD4 T cells (Figure 6), and NK cells (Figure 7), all in the peripheral blood. Some mice showed reduced B220 expression on peripheral blood B cells (Figure 8) as well as reduced CD44 expression on peripheral blood T cells (Figure 9), CD4+ T cells (Figure 10), and CD8+ T cells (Figure 11).
|
Nature of Mutation |
Whole exome HiSeq sequencing of the G1 grandsire identified 64 mutations. All of the above anomalies were linked by continuous variable mapping to mutations in two genes on chromosome 6: Vmn2r27 and Ltbr. The mutation in Ltbr was presumed causative because the marine_ blue phenotype mimics that of other Ltbr alleles (see MGI). The mutation in Ltbr is an A to G transition at base pair 125,312,808 on chromosome 6, corresponding to base pair 1,063 in GenBank genomic region NC_000072. The strongest association was found with a recessive model of inheritance to the B220 expression on peripheral blood B cells phenotype, wherein eight variant homozygotes departed phenotypically from 19 homozygous reference mice and 27 heterozygous mice with a P value of 4.874 x 10-18 (Figure 12). The mutation corresponds to residue 622 in the mRNA sequence NM_010736 within exon 4 of 10 total exons.

The mutated nucleotide is indicated in red. The mutation results in a histidine to arginine substitution at position 141 (H141R) in the LTβR protein, and is strongly predicted by PolyPhen-2 to be damaging (score = 0.983).

Protein Prediction |
Ltbr encodes the lymphotoxin β receptor (LTβR), a member of the tumor necrosis factor receptor (TNFR) superfamily (1). Similar to other members of the TNFR family, LTβR has an extracellular domain (ECD; amino acids 28-221; SMART), a transmembrane domain (TMD; amino acids 222-244), and an intracellular domain (ICD; amino acids 245-415) [(2); reviewed in (3)]. Amino acids 1-27 of LTβR comprise a signal peptide (2). LTβR has two conserved putative Asn-linked glycosylation sites at Asn40 and Asn179 (2). Within the ECD, LTβR has four cysteine-rich domains (CRDs; amino acids 43-80, 83-124, 126-169, and 172-212) [(4); reviewed in (3)]. The CRDs mediate ligand (i.e., LTα1β2 and LIGHT) specificity and affinity [(5;6); reviewed in (3)]. The second and third CRDs (i.e., amino acids 83-124 and 126-169) mediate most receptor-ligand interactions (6). The self-association domain (SAD; amino acids 324-377) within the ICD is required for LTβR-associated apoptotic signaling as well as for the association of LTβR with the serine/threonine kinases p50 and p80 (1;7). The marine_blue mutation results in a histidine to arginine substitution at position 141 (H141R) in the LTβR protein; amino acid 141 is within the third CRD within the ECD. See the record for kama for more information about Ltbr.

Putative Mechanism | LTα1β2 and LIGHT (alternatively, TNF superfamily (TNFSF)14) are the known ligands of LTβR; both LTα1β2 and LIGHT are members of the TNF superfamily [4;8-12); see the record PanR1 (Tnf) and walla (Cd40lg)]. LTα1β2 is expressed on activated T and B lymphocytes as well as natural killer (NK) cells, a subset of follicular B cells, and lymphoid tissue inducer (LTi) cells (CD4+IL-7R+CD3− CD45+RORγt+; see the record for chestnut) (9;13;14). LIGHT is a homotrimer expressed on T lymphocytes, monocytes, granulocytes, and immature dendritic cells (13). LTβR signals through both the canonical (classical; see the record for finlay) and non-canonical (alternative; see the record for xander) nuclear factor κB (NF-κB) signaling pathways [(15-17); reviewed in (18)]. LTβR-mediated activation of the NF-κB signaling pathways results in the expression of genes that encode adhesion molecules, chemokines (e.g., CCL21 and CXCL13), and lymphokines involved in inflammation and secondary lymphoid organogenesis and homeostasis [(16); reviewed in (3)]. For a detailed review on the NF-κB signaling pathways see the records for finlay and xander. LTβR-associated signaling mediates several functions including lymphoid tissue development and maintenance (19-23), formation of germinal centers (24), dendritic cell-mediated immune function (25;26), apoptosis (27), chemokine secretion, maintenance of splenic architecture, maintenance of T and B cell segregation into discrete compartments, protection against autoimmune diseases, regulation of lipid metabolism (28), homeostasis of the intestinal immune system (16) including protection against Citrobacter rodentium-induced colitis (10;29) and DSS-induced colitis (30) as well as protection against Mycbacterium bovis bacillus Calmette-Guérin (BCG), Mycobacterium tuberculosis, Listeria monocytogenes, and cytomegalovirus infections (31-33). LTβR-associated signaling has been linked to several human conditions including autoimmunity, atherosclerosis, and cancer (see descriptions, above). Mutations in LTBR have been linked to increased risk for IgA nephropathy (OMIM: %161950), a form of glomerulonephritis that leads to end-stage renal disease, in Korean children (34). Ltbr knockout (Ltbr-/-; Ltbrtm1Kpf, MGI:2384140) mice appear healthy, are born at the expected Menelian frequency, and are fertile (22). Ltbr-/- mice exhibited defects in secondary lymphoid organogenesis including the absence of cervical, axillary, inguinal, paraaortic/sacral, popliteal, and mesenteric lymph nodes, Peyer’s patches, and germinal centers, disorganization of the splenic architecture (i.e., disturbed microarchitecture of the white pulp, no separate B- and T-cell areas, no follicles, and disruptions to the marginal zone), and disruption of the thymic stroma architecture (21;22;35;36). All of the Ltbr-/- mice had a spleen and a thymus; the spleens of the Ltbr-/- mice were 1.5 to 2 times bigger than those in wild-type mice (22). Thymocyte maturation was normal in the Ltbr-/- mice (22). Within the spleen, the marginal zone B cell population (B220+, IgMhigh, IgDdull), MOMA-1+ metallophilic macrophages, sialoadhesin+ MZ macrophages, and MAdCAM-1+ sinus lining cells were completely undetectable (22). Flow cytometric analysis of lymphocytes from lungs and spleens of the Ltbr-/- mice determined that αEβ7high integrin+ T cells were absent (22). The phenotypes observed in the marine_blue mice indicate loss of LTβRmarine_blue function.
