[HTML][HTML] A protein encoded within the Down syndrome critical region is enriched in striated muscles and inhibits calcineurin signaling

Here we describe a small family of proteins, termed MCIP1 and MCIP2 (for myocyte-
enrichedcalcineurin interacting protein), that are expressed most abundantly in striated
muscles and that form a physical complex with calcineurin A. MCIP1 is encoded byDSCR1,
a gene located in the Down syndrome critical region. Expression of the MCIP family of
proteins is up-regulated during muscle differentiation, and their forced overexpression
inhibits calcineurin signaling to a muscle-specific target gene in a myocyte cell background …
