- Extra Details:
- The annexins are a large family of related proteins which share the property of binding to phophospholipid containing membranes in a Calcium dependent manner (1). Different members of the family were discovered by different laboratories and as a result the various members have many alternate names, such as lipocortin, calpactin, calelectrin and very many others. In fact Annexin A6 has a particularly surprising number of alternate names, 19 being listed on the Genecards ANXA6 site. The widely used current nomenclature is now based on a letter to indicate membership in a particular one of several annexin sub-families and a number for individual gene products, hence the name annexin A6. The annexin family is defined by a compact disc structure formed from 16 closely packed α-helices which co-ordinate multiple Calcium ions with phospholipid containing membranes. This domain is defined by 4 imperfect repeats of a ~77 amino acid sequence, each repeat forming 4 α-helices (2,3). Annexin A6 was first cloned and sequenced as p68, as a Calcium dependent membrane binding protein extracted from B lymphoblastoid cells (4) and independently as the human homolog of calelectrin, a protein isolated from the electric organ of the fish Torpedo (5). The annexin A6 protein sequence was found to be 75kDa in molecular size, about twice the size of most other annexin family members, and proved to have two of the 16 α-helical regions apparently generated by duplication of the annexin core. The protein has frequently been reported to run on SDS-PAGE more rapidly that expected from the expected 75kDa, at ~68kDa, likely related to the high content of negatively charged amino acids (5). Annexin A6 is normally localized in the cytosol but becomes membrane associated following cellular injury, and so is often seen in ““blebs”, transient herniations of the plasma membrane associated with apoptosis and more generally indicative of cell stress. Recent studies suggest that annexin A6 functions, in combination with annexin A4, in the repair of cell membranes following cellular injury (6). 046172 detects protein mainly expressed in spherical cellular membrane protrusions, known as blebs, while the β-tubulin antibody produces strong staining of cytoplasmic microtubules. Applications: Suitable for use in Western Blot and Immunofluorescence/Immunocytochemistry. Not recommended for use in Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 1:10,000-1:20,000 Immunofluorescence (IF-IC): 1:2000-1:5000 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
