Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting,
Specificity / Sensitivity
Phospho-NuMA (Thr2055) Antibody recognizes endogenous levels of NuMA protein only when phosphorylated at Thr2055.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr2055 of human NuMA protein. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of HT-29 cell extracts, untreated (-) or treated with thymidine (2 mM, 16 hr) followed by Nocodazole #2190 (10 nM, 24 hr; +), using Phospho-NuMA (Thr2055) Antibody (upper), NuMA (D49H4) Rabbit mAb #8967 (middle), and α-Actinin (D6F6) XP® Rabbit mAb #6487 (lower).
The nuclear mitotic apparatus protein (NuMA) is a coiled coil protein involved in the formation and maintenance of the mitotic spindle. NuMA plays a role in chromatin organization during interphase, which influences mammary epithelial differentiation (1,2). During apoptosis, carboxy-terminal cleavage of NuMA may amplify signaling in the cell death pathway (2). NuMA is phosphorylated at numerous sites, with phosphorylation at Ser395 occurring in an ATM/ATR-dependent manner in response to DNA damage (3,4).
Phosphorylation at Thr2055 by CDK1 is required for spindle pole association of NuMA at the onset of mitosis. Dephosphorylation by PPP2CA leads to enhancement of NuMA at the cell cortex in anaphase and proper cell-cycle progression (5,6).
