CCM2_C

CCM2_C
PFAM accession number:PF16545
Interpro abstract (IPR032375):

This entry represents the C-terminal folded helical region of cerebral cavernous malformations protein 2 (CCM2, also known as malcavernin), a component of the CCM signalling pathway which is a crucial regulator of heart and vessel formation and integrity [(PUBMED:14624391)]. This domain is structurally homologous to the N-terminal domain of harmonin, so it is named the harmonin-homology domain (HHD). The structure of this domain has been revealed [(PUBMED:23266514)].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry CCM2_C
