pfam13864: Enkurin (This model is not part of the current CDD release)
Calmodulin-binding
This is a family of apparent calmodulin-binding proteins found at high levels in the testis and vomeronasal organ and at lower levels in certain other tissues. Enkurin is a scaffold protein that binds PI3 kinase to sperm transient receptor potential (canonical) (TRPC) channels. The mammalian transient receptor potential (canonical) channels are the primary candidates for the Ca(2+) entry pathway activated by the hormones, growth factors, and neurotransmitters that exert their effect through activation of PLC. Calmodulin binds to the C-terminus of all TRPC channels, and dissociation of calmodulin from TRPC4 results in profound activation of the channel.
