Protein
Testis-specific serine/threonine-protein kinase 2
Gene
Tssk2, Stk22b
Organism
Mus musculus (Mouse)
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 '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

Magnesium By similarity.

Enzyme regulationi

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

Note: Present in the cytoplasm of elongating spermatids. In spermatozoa, localizes in the equatorial segment, neck, the midpiece and in a specific sperm head compartment. In spermatids, concentrates in centrioles during flagellogenesis. Localizes in the tail and acrosomal regions of epididymal sperm.6 Publications

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
