BCCIP Protein, Human (sf9, His-GST)

BCCIP proteins contribute to interphase microtubule organization and anchoring as well as spindle pole organization and stability during mitosis. BCCIP protein may induce cell cycle arrest by enhancing CDK2 inhibition and participate in DNA damage repair through homologous recombination with BRCA2. BCCIP Protein, Human (sf9, His-GST) is the recombinant human-derived BCCIP protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag. The total length of BCCIP Protein, Human (sf9, His-GST) is 314 a.a., with molecular weight of ~65 kDa.

BCCIP, a multifaceted protein, plays crucial roles during interphase and mitosis. In interphase, it is essential for microtubule organizing and anchoring activities, while during mitosis, it contributes significantly to spindle pole organization and stabilization. Notably, isoform 2/alpha emerges as particularly vital in regulating microtubule anchoring, stability, spindle architecture, and orientation, compared to isoform 1/beta. Beyond its structural functions, BCCIP may exert control over the cell cycle by enhancing CDKN1A-mediated inhibition of CDK2 activity, potentially promoting cell cycle arrest. Furthermore, BCCIP may play a role in DNA damage repair through homologous recombination, likely in conjunction with BRCA2, while its involvement in non-homologous end joining (NHEJ) remains unclear. BCCIP engages in diverse interactions, forming complexes with BRCA2, CDKN1A, MTDH/LYRIC, DCTN1/p150-glued, ACTR1A/ARP1, and tubulin subunits. Isoforms 1 and 2 exhibit distinct interaction profiles, with both associating with alpha-, beta-, and gamma-tubulins. Additionally, BCCIP interacts with TENT5C, although this interaction does not impact TENT5C poly(A) polymerase function.
