Summary: Enables magnesium ion binding activity and protein serine/threonine kinase activity. Involved in flagellated sperm motility; peptidyl-serine phosphorylation; and sperm DNA condensation. Is active in axonemal microtubule doublet inner sheath and sperm flagellum. Orthologous to human TSSK6 (testis specific serine kinase 6). [provided by Alliance of Genome Resources, Nov 2024]

What's a GeneRIF?

TSSK6 is required for gammaH2AX formation during spermiogenesis, and also link gammaH2AX to the histone-to-protamine transition and male fertility.
Title: TSSK6 is required for γH2AX formation and the histone-to-protamine transition during spermiogenesis.
HSP90 function abolished the catalytic activities of TSSK4 and -6 but did not significantly alter the specific activities of TSSK1 and -2. Inhibition of HSP90 resulted in increased TSSK ubiquitination and proteasomal degradation
Title: Heat shock protein 90 functions to stabilize and activate the testis-specific serine/threonine kinases, a family of kinases essential for male fertility.
HSP90 is essential for functional maturation of the kinase and identify SIP as a cochaperone that is critical to the HSP90-mediated activation of SSTK.
Title: Identification of a novel HSP70-binding cochaperone critical to HSP90-mediated activation of small serine/threonine kinase.
results demonstrate that SSTK is required for proper postmeiotic chromatin remodeling and male fertility
Title: Identification and characterization of SSTK, a serine/threonine protein kinase essential for male fertility.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
