CC -!- FUNCTION: Probable phosphatase which plays a redundant role with gsp-4
CC in spermatogenesis by regulating sister chromatid segregation during
CC meiosis (PubMed:16943775, PubMed:22042574). In addition, involved in
CC sperm motility by controlling the dynamic disassembly of major sperm
CC proteins (MSP) in the spermatozoan pseudopodium (PubMed:22042574).
CC {ECO:0000269|PubMed:16943775, ECO:0000269|PubMed:22042574}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + O-phospho-L-seryl-[protein] = L-seryl-[protein] +
CC phosphate; Xref=Rhea:RHEA:20629, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC ChEBI:CHEBI:61977; EC=3.1.3.16;
CC Evidence={ECO:0000255|RuleBase:RU004273};
CC -!- SUBCELLULAR LOCATION: Chromosome {ECO:0000269|PubMed:16943775}. Cell
CC projection, pseudopodium {ECO:0000269|PubMed:22042574}. Cytoplasm
CC {ECO:0000269|PubMed:22042574}. Note=Co-localizes with MSP in oblong
CC stripes in the cytoplasm of inactive sperm and in the pseudopodium in
CC activated sperm. {ECO:0000269|PubMed:22042574}.
CC -!- TISSUE SPECIFICITY: Expressed in male germline including spermatocytes,
CC spermatids and spermatozoa. {ECO:0000269|PubMed:16943775,
CC ECO:0000269|PubMed:22042574}.
CC -!- DEVELOPMENTAL STAGE: Expressed at all stages of spermatocyte meiosis.
CC {ECO:0000269|PubMed:16943775, ECO:0000269|PubMed:22042574}.
CC -!- DISRUPTION PHENOTYPE: No obvious phenotype (PubMed:22042574).
CC Simultaneous RNAi-mediated knockdown of gsp-3 and gsp-4 results in male
CC sterility due to chromosome segregation defects during sperm meiosis
CC (PubMed:16943775). gsp-3 and gsp-4 double mutant hermaphrodites have
CC egg laying defects and no viable progeny. gsp-3, gsp-4 and him-8 triple
CC mutants have incomplete separation of sister chromatids during the
CC second meiotic segregation. Mislocalization of MSP in activated sperm.
CC In addition, have partial reduction in mpk-1 phosphorylation and air-2
CC association with bivalent chromosomes in the most proximal oocyte in
CC response to MSP (PubMed:22042574). {ECO:0000269|PubMed:16943775,
CC ECO:0000269|PubMed:22042574}.
CC -!- SIMILARITY: Belongs to the PPP phosphatase family.
CC {ECO:0000255|RuleBase:RU004273}.
CC -!- CAUTION: Due to the high similarity between gsp-3 and gsp-4, the
CC antibody used to study expression does not distinguish between the two
CC proteins. {ECO:0000303|PubMed:16943775, ECO:0000303|PubMed:22042574}.
