Protein

Testis-specific serine/threonine-protein kinase 2

Gene

TSSK2

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Testis-specific serine/threonine-protein kinase required during spermatid development. Phosphorylates TSKS at 'Ser-288' and SPAG16. Involved in the late stages of spermatogenesis, during the reconstruction of the cytoplasm. During spermatogenesis, required for the transformation of a ring-shaped structure around the base of the flagellum originating from the chromatoid body.3 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.1 Publication

Cofactori

Magnesium.1 Publication

Enzyme regulationi

Activated by phosphorylation on Thr-174, potentially by autophosphorylation.By similarity
