    SF3A3 Antibody recognizes endogenous levels of total SF3A3 protein.

    Species Reactivity:

    Human, Mouse, Rat, Monkey

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu495 of human SF3A3 protein. Antibodies are purified by peptide affinity chromatography.

    Background

    The mammalian splicing factor SF3a contains three primary subunits: SF3A1 (SF3a120), SF3A2 (SF3a66), and SF3A3 (SF3a60) which, along with SF3b, activate the U2 snRNP to form the pre-mRNA splicing complex (1,2). SF3A2 and SF3A3 both interact with SF3A1, but not with each other, and SF3A3 plays a major role in recruiting SF3A1 to the complex (3). Each protein in the heterotrimer has been shown to be essential for mRNA splicing and cell viability (4). Notably, SF3a plays a role in growth factor signaling as SF3A1 can bind to ERalpha when phosphorylated at Ser118 to affect downstream splicing (5). SF3a also plays a role in the innate immune response, as it promotes inflammation by splicing the TLR adaptor Myd88. Furthermore, SF3a regulates a number of genes involved in innate immune signaling pathways in macrophages versus other pathways (6,7).
