Testis-specific serine/threonine-protein kinase 1

Gene

Tssk1b

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. 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.1 Publication

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

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
