    Summary
    Predicted to enable microtubule binding activity. Involved in homologous chromosome orientation in meiotic metaphase I and positive regulation of meiosis I spindle assembly checkpoint. Located in cytoplasm and kinetochore. Is expressed in cerebral cortex ventricular layer; telencephalon; and telencephalon ventricular layer. Human ortholog(s) of this gene implicated in primary autosomal recessive microcephaly; primary autosomal recessive microcephaly 4; and sarcoma. Orthologous to human KNL1 (kinetochore scaffold 1).

This triggers rapid p53 activation and robust apoptotic and microglial phagocytic responses that extensively eliminate cells with somatic genome damage, thus causing microcephaly.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
