UniProtKB - Q93380 (UNC93_CAEEL)
Putative potassium channel regulatory protein unc-93
unc-93
Functioni
May contribute to coordination of muscle contraction as regulatory subunit of a nonessential potassium channel complex (PubMed:1313436, PubMed:14534247).
Plays a role in the formation of muscle connections, also called muscle arm extensions, between the body wall and the motor axons in the dorsal and ventral cord (PubMed:27123983).
