Anti-ACT (Activator of cAMP Responsive Element Modulator (CREM) in Testis, Activator of CREM in Test

FHL proteins are tissue specific cofactors of CREB and CREM and participate in regulation of various physiological processes. These proteins are characterized by the presence of 4 LIM domains and a LIM-half domain at the N-terminus. ACT, a 33kD protein, is a novel member of this family. It is specifically expressed in male testis and consists of a central activation domain. It is coordinately expressed with CREM and plays a vital role in spermatogenesis. It binds specifically to CREM and powerfully stimulates its transcriptional activation, essential for differentiation of spermatids into mature spermatozoa. It activates CREM in a phosphorylation- and CBP-independent manner. Protein-protein interactions with a Kinesin KIF17B regulate ACT activity in mouse. Applications: Suitable for use in Western Blot.
