Anti-NuMA1 Antibody, clone AD6-1

Nuclear mitotic apparatus protein 1 (UniProt: Q14980; also known as NuMA protein, Nuclear matrix protein-22, NMP-22, SP-H antigen) is encoded by the NUMA1 (also known as NMP22, NUMA) gene (Gene ID: 4926) in human. NMP-22 is a homodimeric nuclear protein that is highly abundant component of the nuclear matrix where it may serve a non-mitotic structural role and occupies the majority if the nuclear volume. It is required for maintenance and establishment of the mitotic spindle poles during symmetric cell divisions, functioning as a tether linking bulk microtubules of the spindle to centrosomes. It is also considered to be essential or proper alignment of the mitotic spindle during asymmetric cell divisions. NMP-22 resides in the nuclear matrix during interphase and then dissociates from condensing chromosomes during early prophase and relocates to the spindle poles via dynein/dynamin association and it remains there until the anaphase onset. As mitosis progresses it re-associates with telophase chromosomes very early during nuclear reformation, before substantial accumulation of lamins on chromosomal surfaces is evident. NMP-22 is phosphorylated in the C-terminal tail during mitosis, most likely by CDK1 and phosphorylation increases its solubility and promotes association with dynein and subsequent translocation to the spindle poles. O-glycosylation during cytokinesis at sites identical or close to phosphorylation sites interferes with the phosphorylation status of NMP-22.
