Although their exact biological function is not fully understood, NS are believed to function as hubs for mRNA splicing and potentially transcription (1). The splicing factors serine\/arginine repetitive matrix protein 2 (SRRM2) and SON are necessary for NS formation (2). SRRM2 and SON undergo phase separation and function as scaffolding proteins, recruiting additional splicing factors and promoting NS assembly (3). In Alzheimer's disease (AD) and other tauopathies, SRRM2 can become mislocalized from NS to pathological tau aggregates in the cytoplasm, resulting in aberrant splicing (4,5). Loss-of-function (LoF) mutations in SRRM2 have also been associated with neurodevelopmental delay and an increased risk of developing papillary thyroid carcinoma (PTC) (6,7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n300 kDa nuclear matrix antigen; 300-KD; Cwc21; CWF21; DKFZp667L0421; DKFZp686O15166; FLJ21926; FLJ22250; HSPC075; KIAA0324; MGC40295; RNA binding protein; Ser\/Arg-related nuclear matrix protein of 300 kDa; serine\/arginine repetitive matrix 2; Serine\/arginine repetitive matrix protein 2; Serine\/arginine-rich splicing factor-related nuclear matrix protein of 300 kDa; Splicing coactivator subunit SRm300; SR-related nuclear matrix protein of 300 kDa; SRL300; SRM300; SRRM2; Tax-responsive enhancer element-binding protein 803; TaxREB803; testicular secretory protein Li 53\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 200-300\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46797642334377,"sku":"19700S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-19700s","provider":"Iright","version":"1.0","type":"link"}
