TESK1
This gene product is a serine/threonine protein kinase that contains an N-terminal protein kinase domain and a C-terminal proline-rich domain. Its protein kinase domain is most closely related to those of the LIM motif-containing protein kinases (LIMKs). The encoded protein can phosphorylate myelin basic protein and histone in vitro. The testicular germ cell-specific expression and developmental pattern of expression of the mouse gene suggests that this gene plays an important role at and after the meiotic phase of spermatogenesis.

Interaction
Interacts (via both C- and N-termini) with SPRY4 (via C-terminus); the interaction inhibits TESK1 kinase activity (PubMed:12027893, PubMed:15584898). Interacts with TAOK1; the interaction inhibits TAOK1 kinase activity (By similarity). Interacts (via C-terminus) with SPRED1 (via C-terminus); the interaction inhibits TESK1 kinase activity (PubMed:18216281). Interacts (via C-terminus) with PARVA/PARVIN (via C-terminus); the interaction inhibits TESK1 kinase activity (PubMed:15817463). Interacts with YWHAB/14-3-3 beta; the interaction is dependent on the phosphorylation of TESK1 Ser-437 and inhibits TESK1 kinase activity (PubMed:11555644). Interacts with SPRY1, SPRY3 and SPRED2 (PubMed:17974561). Interacts (via C-terminus) with SPRY2 (via C-terminus); the interaction disrupts SPRY2 interaction with PPP2CA/PP2A-C, possibly by vesicular sequestration of SPRY2 (PubMed:17974561). Therefore dephosphorylation of SPRY2 by the serine/threonine-protein phosphatase 2A (PP2A) holoenzyme is lost, inhibiting its interaction with GRB2 (PubMed:17974561).
