产品说明
一般描述
The actin-related protein Arp1α (centractin, actin-RPV), a member of the superfamily of actin-related proteins (Arp), is the major subunit of the dynactin complex, a key component of the cytoplasmic dynein motor machinery. It has been shown to localize to multiple structures within the cell, including membrane organelles, the centrosome, spindle poles, and spindle pole microtubules during mitosis and prometaphase kinetochores.
免疫原
synthetic peptide corresponding to the mid-region of human Arp1α/centractin (amino acids 222-240). This sequence is identical in mouse and dog Arp1α/centractin, highly conserved (89% identity) in the α-centractin isoform, and not found in known actin isoforms.
应用
Anti-Arp1α/Centractin antibody produced in rabbit has been used in immunoblotting and immunofluorescence staining.
生化/生理作用
The actin-related proteins (Arp)1α/dynactin complex regulates dyne mediated vesicle movement on microtubules as well as spindle assembly and cell division. Arp1α overexpression in cells results in aberrant spindle morphologies and cell cycle delay at prometaphase, suggesting a possible function of Arp1α/dynactin complex in progression through the prometaphase of mitosis. Expression of mutant Arp1a protein has no effect on mitotic cells, but results in microtubule disruption in interphase cells, by destabilizing the interaction between Arp1a and components of the dynactin complex and nuclear mitotic apparatus protein (NuMA).
Arp1α or Centractin is an actin-related, ubiquitious protein that forms a part of the dynactin complex and is associated with centrosomes. Studies have reported that centractin interacts with spectrin and subsequently provides a link for dynactin to associate with organelles in cells.
