Dual specificity testis-specific protein kinase 1 is an enzyme that in humans is encoded by the TESK1 gene.^[4][5]

Function

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.^[5]

Interactions

TESK1 has been shown to interact with YWHAB^[6] and SPRY4.^[7]
