Summary: Predicted to enable identical protein binding activity and kinetochore binding activity. Acts upstream of or within negative regulation of T cell proliferation; regulation of mitotic cell cycle phase transition; and thymus development. Located in cytoplasm; kinetochore; and spindle pole. Part of MAD1 complex and mitotic spindle assembly checkpoint MAD1-MAD2 complex. Is expressed in brain; cerebral cortex; future brain; hippocampus; and telencephalon. Human ortholog(s) of this gene implicated in lymphoma; mosaic variegated aneuploidy syndrome 7 with inflammation and tumor predisposition; and prostate cancer. Orthologous to human MAD1L1 (mitotic arrest deficient 1 like 1). [provided by Alliance of Genome Resources, Jul 2025]
Expression: Ubiquitous expression in thymus adult (RPKM 39.3), ovary adult (RPKM 12.6) and 28 other tissues See more

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.

RNA

NR_152617.1 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (4) lacks an alternate exon compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
