SFPQ belongs to the behavior\/human splicing (DBHS) protein family along with paraspeckle protein 1 (PSPC1) and non-POU domain-containing octamer-binding protein (NONO) (1). DBHS proteins are a unique family of RNA-binding proteins that recruit various proteins and nucleic acids involved in transcriptional activation and repression, transcript localization, splicing, and DNA damage repair (2). SFPQ and NONO are also core components of paraspeckles, which are subnuclear bodies distinct from nuclear speckles that are defined by the colocalization of SFPQ, NONO, and other proteins with the long noncoding RNA NEAT1 (2). The biological function of paraspeckles is currently unknown, but they are believed to be important for gene regulation in the presence of cellular stressors (3). Although SFPQ is typically localized to the nucleus, multiple studies indicate that cytoplasmic SFPQ levels are important for proper motor neuron differentiation and maintenance (4,5). has also been linked to multiple neurological disorders, including Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS) (6-9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n100 kDa DNA-pairing protein; DNA-binding p52\/p100 complex, 100 kDa subunit; epididymis secretory sperm binding protein; hPOMp100; polypyrimidine tract binding protein associated; polypyrimidine tract-binding protein-associated splicing factor; Polypyrimidine tract-binding protein-associated-splicing factor; POMP100; PPP1R140; protein phosphatase 1, regulatory subunit 140; PSF; PTB-associated splicing factor; PTB-associated-splicing factor; SFPQ; splicing factor proline and glutamine rich; splicing factor proline\/glutamine rich (polypyrimidine tract binding protein associated); splicing factor proline\/glutamine rich (polypyrimidine tract-binding protein-associated); splicing factor proline\/glutamine-rich; splicing factor proline\/glutamine-rich (polypyrimidine tract binding protein associated); Splicing factor, proline- and glutamine-rich\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 65, 75, 100\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799876096169,"sku":"71992S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-71992s","provider":"Iright","version":"1.0","type":"link"}
