klp-19 encodes a plus-end-directed microtubule motor protein that is most closely related to motors of the kinesin-4 family; KLP-19 activity is essential for embryonic and larval development and is required for generating a force that aligns sister chromatid kinetochores directly opposite the spindle poles thus ensuring proper holocentric chromosome segregation; KLP-19 expression is detected in embryos and in the gonad, where it is most strongly expressed in distal mitotic nuclei and in late meiotic prophase nucleoplasm; during meiosis and mitosis, KLP-19 expression is dynamic and is detected in the nucleoplasm, the spindle body, in association with condensed chromosomes (particularly between homologous chromosomes), and in the spindle interzone.
Predicted to enable ATP hydrolysis activity; microtubule binding activity; and microtubule motor activity. Involved in meiotic chromosome condensation and meiotic spindle midzone assembly. Located in condensed nuclear chromosome; nucleoplasm; and spindle. Expressed in germ line. Human ortholog(s) of this gene implicated in non-syndromic X-linked intellectual disability 100. Is an ortholog of human KIF4A (kinesin family member 4A).

Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
