Associated Protein Comments
MIZIP (ZMYND19; Q96E35) colocalizes with MCH1 receptor in HEK293 cells when the proteins are coexpressed using a yeast two-hybrid system [12]. The interaction occurs at the C-terminus of the receptor.
Neurochondrin (NCDN; Q9UBB6) and periplakin (PPL; O60437) both inhibit GTPγS binding, GIRK activity and Ca2+ mobilisation in HEK293 cells when the proteins are coexpressed using a yeast two-hybrid system [26,62]. Again, the interactions occur at the C-terminus of the receptor.
In cotransfected HEK293 cells RGS8 (P57771) inhibits Gi/o and Gq-dependent Ca2+ mobilisation via an interaction within the third cytoplasmic loop [55]. In similar experiments RGS2 (P41220) inhibits Gq-dependent Ca2+ mobilisation [56].
