MYND domain specific interaction of the melanin-concentrating hormone receptor 1 interacting zinc-finger protein with alpha- and beta-tubulin.

MIZIP was originally identified as a highly conserved zinc-finger protein from human brain interacting with the C-terminus of the melanin-concentrating hormone receptor 1. However, the cellular functions of MIZIP are still not known. Here, we focussed on the identification of associated proteins using affinity purification from human cells. This resulted in the identification of alpha- and beta-tubulin. The interaction was confirmed in vitro and in vivo using GST pull-down and immunoprecipitation assays, and was mapped to the MYND zinc-finger of MIZIP and to the N-terminus of tubulin. Immunoprecipitation and immunocytochemistry analyses demonstrate that MIZIP binds to tubulin but not to cellular microtubules in vivo and that ectopic expression of MIZIP does not interfere with the overall structure of the microtubular cytoskeleton. Our results suggest that MIZIP might play an important role in mammalian cells by associating with tubulin and thus might provide a link between MCHR1 and tubulin functions.[1]
