Anti-TROVE2/SS-A/RO60 Antibody Picoband®

Enables RNA binding activity. Involved in cellular response to interferon-alpha and regulation of gene expression. Located in cytosol and nucleoplasm. Part of ribonucleoprotein complex. The cDNA that encodes the 60-kD Ro/SSA autoantigen recognized by autoantibodies in certain lupus erythematosus (152700) and Sjogren syndrome (270150) sera was cloned and sequenced by Deutscher et al. (1988) and confirmed with minor differences by Ben-Chetrit et al. (1989) .

Vacuolar protein sorting-associated protein 4B; Cell migration-inducing gene 1 protein; Suppressor of K (+) transport growth defect 1; Protein SKD1; VPS4B; SKD1; VPS42; MIG1

Involved in late steps of the endosomal multivesicular bodies (MVB) pathway. Recognizes membrane-associated ESCRT-III assemblies and catalyzes their disassembly, possibly in combination with membrane fission. Redistributes the ESCRT-III components to the cytoplasm for further rounds of MVB sorting. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growth factor receptors, lysosomal enzymes and lipids. In conjunction with the ESCRT machinery also appears to function in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis and enveloped virus budding (HIV-1 and other lentiviruses) . VPS4A/B are required for the exosomal release of SDCBP, CD63 and syndecan.

At -20°C for one year from date of receipt. After reconstitution, at 4°C for one month. It can also be aliquotted and stored frozen at -20°C for six months. Avoid repeated freezing and thawing.
