8.A.119.  The  Potassium Channel Regulatory Protein Sup-10 (Sup-10) Family 

The proteins within this family seem to have multiple functions.  One of these is to coordinate muscle contraction as a regulatory subunit of nonessential potassium channel complexes such as the Sup-9 K+ channel of C. elegans (TC# 1.A.1.9.7).  It also forms a complex with MFS protein Unc-93 which may also play a regulatory role in this complex (de la Cruz et al. 2003).
