Summary: Predicted to enable several functions, including disordered domain specific binding activity; dynein complex binding activity; and microtubule binding activity. Involved in several processes, including establishment of mitotic spindle orientation; positive regulation of BMP signaling pathway; and positive regulation of keratinocyte differentiation. Located in lateral cell cortex; mitotic spindle pole; and nuclear matrix. Is expressed in several structures, including 1st branchial arch mandibular component; early embryo; facial prominence; oocyte; and telencephalon. Orthologous to human NUMA1 (nuclear mitotic apparatus protein 1). [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.
