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 & 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).
