human ... TSSK1B(83942)

General description

TSSK1B (testis-specific serine kinase 1B) is a member of a unique subfamily of protein kinases belonging to the AMPK branch on the human kinome tree. TSSK1B is a serine/threonine kinases that is highly expressed in testis and lower express in pancreas, and weak expression in a few other tissues. TSSK members are present in the equatorial segment of human sperm. TSSK1B share 72% amino acid identity and 83% identity in the kinase domain with other family TSSK members and the TSSK1 gene is intronless. In vitro kinase assay shows phosphorylation of TSKS by TSSK1 and TSSK2.

Physical form

Supplied in 50mM Tris-HCl, pH 7.5, 150mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25mM DTT, 0.1mM PMSF, 25% glycerol.

Preparation Note

Two members of the human testis-specific serine/threonine (Ser/Thr) kinase family, TSSK 1 and TSSK 2, were cloned and sequenced from a human testis adaptor-ligated cDNA library using a PCR strategy. Within the cDNA, open reading frames (ORF) were defined encoding
