Summary: Predicted to enable microtubule binding activity. Involved in establishment of meiotic spindle orientation and spindle assembly involved in female meiosis. Located in meiotic spindle. Is expressed in several structures, including alimentary system; brain; early conceptus; genitourinary system; and respiratory system. Orthologous to human SKA2 (spindle and kinetochore associated complex subunit 2). [provided by Alliance of Genome Resources, Dec 2024]

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.
