MA3-061 detects alpha-adaptin from bovine, chicken, frog, human, monkey, mouse, pig and rat. This antibody detects the products of both alpha-adaptin genes, alphaA and alphaC, as well as an alternatively spliced isoform of alphaA found in neurons.
MA3-061 has been successfully used in Western blot, immunofluorescence, and immunoprecipitation procedures. By Western blot, this antibody recognizes an ~100 kDa doublet representing the two isoforms of alpha-adaptin from pig brain extract. Immunofluorescence staining of alpha-adaptin in transfected COS cells with MA3-061A yields distinct punctate dots on the plasma membrane.
The MA3-061 antigen is purified bovine brain adaptor complexes.
Clathrin-mediated endocytosis is the pathway by which many receptors for nutrients and hormones are internalized to be recycled or down-regulated. During formation of clathrin coated membranes, clathrin co-assembles with heterotetrameric molecules known as assembly polypeptides (APs) or adaptors which form a layer of protein between the clathrin lattice and the membrane.
There are two characterized adaptors AP1 and AP2. AP1 is associated with clathrin coated vesicles at the trans-Golgi network and AP2 is associated with the endocytic clathrin coated vesicles at the plasma membrane and has been shown to specifically interact with Src homologous and collagen-like (Shc) and epidermal growth factor (EGF) receptor. AP2 is composed of four subunits, two separate 100 kDa gene products with similar domain structures (alpha and beta adaptin) and a 50 and 17 kDa subunit. There are two alpha-adaptin genes, alphaA and alphaC which have a tissue specific pattern of expression.
