1. Agouti signalling protein (132 aa), the human homologue of mouse agouti, which inhibits melanogenesis by binding to the melanocyte stimulating hormone (MSH) receptor and blocking α-MSH signalling. Variation in the gene encoding ASIP affects hair and eye pigmentation. ASIP may also affect adipocyte function.
2. Atypical protein kinase C isotype-specific interacting protein interacts with PKC-(lambda and -zeta and when overexpressed, inhibits insulin-induced glucose uptake.
