CC -!- FUNCTION: May play a role in sperm motility, especially in the
CC regulation of flagellar function. {ECO:0000269|PubMed:10647005}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-
CC threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060,

CC EC=2.7.11.1; Evidence={ECO:0000269|PubMed:10647005};
CC -!- TISSUE SPECIFICITY: Testis-specific. Expressed in the testis from 22
CC days postpartum (22 dpp). {ECO:0000269|PubMed:10647005}.
CC -!- MISCELLANEOUS: Encoded on the T-complex, a region of 20-30 Mb on
CC proximal third of mouse chromosome 17. Naturally occurring variant
CC forms of the T-complex, known as complete t-haplotypes, are found in
CC wild mouse populations. The t-haplotypes contain at least four
CC nonoverlapping inversions that suppress recombination with the wild-
CC type chromosome, and lock into strong linkage disequilibrium loci
CC affecting normal transmission of the chromosome, male gametogenesis and
CC embryonic development.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CAMK Ser/Thr
CC protein kinase family. Smok subfamily. {ECO:0000305}.
