Testis-specific serine/threonine-protein kinase 2

Gene

Tssk2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Testis-specific serine/threonine-protein kinase required during spermatid development. Phosphorylates 'Ser-281' of TSKS 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.4 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.

Cofactori

Mg2+By similarity

Enzyme regulationi

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

Pathology & Biotechi

Disruption phenotypei

Male mice lacking Tssk1b and Tssk2 are sterile due to haploinsufficiency. chimeras show failure to form elongated spermatids, apoptosis of spermatocytes and spermatids, and the appearance of numerous round cells in the epididymal lumen. Elongating spermatids possess a collapsed mitochondrial sheath.2 Publications
