MGI Phenotype

FUNCTION: This gene encodes a member of a disintegrin and metalloprotease (ADAM) family of endoproteases that play important roles in various biological processes including cell signaling, adhesion and migration. This gene is expressed in a regulated fashion during early stages of spermatogenesis. The encoded preproprotein undergoes proteolytic processing to generate a mature, functional protein. This gene is located in a cluster of related ADAM genes on chromosome 8. [provided by RefSeq, May 2016]
PHENOTYPE: Homozygous mutant mice exhibit enhanced motor coordination during inverted screen testing when compared with that of controls. [provided by MGI curators]

Nature of Mutation

DNA sequencing using the SOLiD technique identified a G to C transversion at position 754 of the Adam18 transcript in exon 9 of 20 total exons. Two transcripts of the Adam18 gene are displayed on Ensembl and Vega. The mutated nucleotide causes a leucine to phenylalanine substitution at amino acid 232 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Adam18 gene encodes a 763 amino acid disintegrin and metalloproteinase domain-containing protein 18 (Uniprot Q9R157). ADAMs are a family of cell surface proteins with a domain structure composed of a signal sequence, a prodomain with a cysteine switch, a metalloproteinase-like domain, a disintegrin-like domain, a cysteine-rich domain, a transmembrane domain, and a C-terminal cytoplasmic domain. These proteins function as proteases to cleave a variety of substrates, but ADAM18 seems to be non-catalytic as its zinc-binding motif contains a variant amino acid. ADAM18 is expressed specifically in the testis, and may be involved in spermatogenesis and fertilization. A tripeptide motif (ECD) within the disintegrin-like domain could be involved in the binding to egg integrin receptor and thus could mediate sperm/egg binding.

The L232F change is located in the peptidase domain, and is predicted to be possibly damaging by the PolyPhen program (see report).
