| _-Actinin 4 (N-terminal) Antibody |
| WB |
| The antibody detects a 100 kDa* protein corresponding to the molecular mass of _-actinin 4 on SDS-PAGE immunoblots of human A431 cells and rabbit spleen fibroblasts. This sequence is well conserved in rat and mouse _-actinin 4, but is not conserved in other _-actinins. |

| Specifications |
| Unconjugated |
| Rabbit |
| _-Actinin 4 synthetic peptide (coupled to carrier protein) corresponds to amino acids in the N-terminus of human _-actinin 4. |
| Polyclonal |
| #REF! |
| IgG |
| Antigen Affinity purification |
| PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol |
| Storage at -20C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20C. |

| a-actinin 4, actinin alpha4 |
| _-Actinins are widely expressed cytoskeletal proteins that cross-link actin filaments through anti-parallel homodimers of the rod domains. Four _-actinin genes have been discovered in humans with _-actinin 1 and 4 being widely expressed in non-muscle cells. _-Actinins contain three conserved domains that include an N-terminal actin binding domain, four spectrin-like repeats in the central region, and a C-terminal calmodulin binding domain. _-Actinin cross-links the actin filament networks and associates the network to focal adhesion sites through binding of talin and vinculin. _-Actinin 1 is phosphorylated at Tyr-12 by FAK, while _-actinin 4 can be phosphorylated at Tyr-4 and Tyr-31 after EGF treatment. Tyr-4 and Tyr-31 phosphorylation inhibit actin binding and reduces actin-filament driven multi-nucleation in rat kidney cells. Thus, phosphorylation in _-actinins may be important for regulating actin binding and actin cytoskeletal remodeling. |
