ACT (Activator of cAMP Responsive Element Modulator (CREM) in Testis, Activator of CREM in Testis, dJ393D12.2, Four and a Half LIM Domains Protein 5, FHL5, FHL-5 Protein, FLJ33049, KIAA0776)

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.\n\nApplications:\nSuitable for use in Western Blot.
