Tissue Specificity | Expressed only in the testis. |
Post Translational Modifications | Activated by autophosphorylation on Thr-197. ODF2 potentiates the autophosphorylation activity of TSSK4 at Thr-197. Ubiquitinated.HSP90 activity negatively regulates ubiquitination and degradation. |
Function | Serine/threonine kinase which is involved in male germ cell development and in mature sperm function. May be involved in the Cre/Creb signaling pathway. Phosphorylates CREB1 on 'Ser-133' in vitro and can stimulate Cre/Creb pathway in cells. Phosphorylates CREM on 'Ser-116' in vitro. Phosphorylates ODF2 on 'Ser-95'. |
