What's a GeneRIF?

In mouse testis, PPP1CC2 can form a complex with TSSK1 mediated by the direct interaction of each with the kinase substrate protein TSKS. Interaction between PPP1CC2 and TSKS is mediated through an RVxF docking motif on the TSKS surface.
Title: PPP1CC2 can form a kinase/phosphatase complex with the testis-specific proteins TSSK1 and TSKS in the mouse testis.
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.
Tssk1 and Tssk2 play an important role in the regulation of sperm function.
Title: [Cloning and expression of Tssk1 & Tssk2 in mice and the presence & localization of them in mature sperm].
Results reveal TSSK1- and TSSK2-dependent functions of a transformed chromatoid body in post-meiotic cytodifferentiation of spermatids.
Title: Functional transformation of the chromatoid body in mouse spermatids requires testis-specific serine/threonine kinases.
Deletion of Tssk2 kinase/substrate pair is predicted to play an indispensable role during spermiogenesis
Title: TSKS concentrates in spermatid centrioles during flagellogenesis.
Results confirm both TSSK 2 and TSKS persist in sperm, define a critical role of TSKS' N-terminus in enzyme interaction, identify Ser 281 as a TSKS phosphorylation site and indicate an indispensable role for TSSK 1 and 2 in spermiogenesis.
Title: Targeted deletion of Tssk1 and 2 causes male infertility due to haploinsufficiency.
The expression patterns of Tsk1 is documented throughout spermiogenesis showing an initial association of Tsk1 with cells in meiotic metaphase.
Title: Immunohistochemical analysis of the expression of two serine-threonine kinases in the maturing mouse testis.

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.
