ELKS/Rab6-interacting/CAST family member 1 (ERC1)

Regulatory subunit of the IKK complex.

Probably recruits IkappaBalpha/NFKBIA to the complex.

May be involved in the organization of the cytomatrix at the nerve terminals active zone (CAZ) which modulates neurotransmitter release. May be involved in vesicle trafficking at the CAZ.
