Anti-SWAP70 Antibody Picoband® 0,00647 Vervoeging

SWAP70 (Switch-associated protein 70) is a 67-70 kDa intracellular protein that bears limited resemblance to members of the Dbl-family of GEFs for small Rho GTPases. It is expressed in mast cells, dendritic cells and B cells. In mast cells, it promotes the release of anaphylactic mediators; in dendritic cells, it regulates the appearance of MHC II; and in B cells, it forms a nuclear complex that initiates immunoglobulin class switching. Human SWAP70 is 585 amino acids (aa) in length. It contains one plextrin homology (PH) domain (aa 213-304) plus a coiled-coil region (aa 316-539) . There are three potential splice variants. One contains an alternative start site at Met70, another shows a deletion of aa 81-138, and a third possesses a 38 aa substitution for aa 453-585. Over aa 386-585, human SWAP70 shares 96% aa identity with mouse SWAP70.

E.coli-derived human SWAP70 recombinant protein (Position: H161-K292) .

Expressed in basement membranes of lung and kidney. Muscle- and neuron-specific isoforms are found. Isoforms (y+) with the 4 AA insert and (z+8) isoforms with the 8 AA insert are all neuron-specific. Isoforms (z+11) are found in both neuronal and non-neuronal tissues.

Catalyzes the NADPH-dependent reduction of succinic semialdehyde to gamma-hydroxybutyrate. May have an important role in producing the neuromodulator gamma-hydroxybutyrate (GHB) . Has broad substrate specificity. Has NADPH-dependent aldehyde reductase activity towards 2-carboxybenzaldehyde, 2-nitrobenzaldehyde and pyridine-2-aldehyde (in vitro) . Can reduce 1,2-naphthoquinone and 9,10-phenanthrenequinone (in vitro) . Can reduce the dialdehyde protein-binding form of aflatoxin B1 (AFB1) to the non-binding AFB1 dialcohol. May be involved in protection of liver against the toxic and carcinogenic effects of AFB1, a potent hepatocarcinogen.
