Cadherin_C_2

Cadherin_C_2
PFAM accession number:PF16492
Interpro abstract (IPR032455):

This entry represents the cytoplasmic C-terminal domain of some proto-cadherins. It is this region of the cadherins that allows cell-adhesion and the essential feature of metazoan multicellularity. Cadherins are cell-surface receptors that function in cell adhesion, cell polarity, and tissue morphogenesis [(PUBMED:1568244), (PUBMED:22837400)].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Cadherin_C_2
