TMEM37

TMEM37
PFAM accession number:PF15108
Interpro abstract (IPR029372):

Voltage-dependent calcium channel gamma-like subunit (also known as Tmem37) has a role in stabilising the calcium channel in an inactivated (closed) state. It is a subunit of the L-type calcium channels that modulate calcium current when coexpressed with CACNA1G (calcium channel, voltage-dependent, T type, alpha 1G subunit) [ (PUBMED:10734232) ].

GO component:integral component of membrane (GO:0016021)
GO function:voltage-gated ion channel activity (GO:0005244), calcium channel activity (GO:0005262)
