Summary

ADAM23 (ADAM metallopeptidase domain 23, HGNC:202) is a protein-coding gene on chromosome 2q33.3, encoding Disintegrin and metalloproteinase domain-containing protein 23 (O75077). May play a role in cell-cell and cell-matrix interactions.

This gene encodes a member of the ADAM (a disintegrin and metalloprotease domain) family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins and have been implicated in a variety of biological processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. It is reported that inactivation of this gene is associated with tumorigenesis in human cancers.
