Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nTMEM41B (also known as Stasimon) was discovered as a target of splicing dysfunction induced by loss of spinal motor neuron (SMN) protein, a feature of spinal muscular atrophy (SMA), resulting in motor circuit defects (1). Loss of TMEM41B in mice results in embryonic lethality (2). TMEM41B is a transmembrane protein that resides at the endoplasmic reticulum (ER) and is found at contact sites between the ER and mitochondria (2). Independent CRISPR screens identified TMEM41B as a novel regulator of autophagy, being structurally and functionally related to VMP1 (3-5). Loss of TMEM41B inhibited autophagosome formation and autophagic flux (3-5). Furthermore, depletion of TMEM41B led to an accumulation of lipid droplets, indicating a role in lipid mobilization and utilization of fatty acids (3,4). TMEM41B also appeared in screens, identifying it as an essential host protein for infection of flaviviruses and coronaviruses, including SARS-CoV-2 (6,7).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nKIAA0033; MGC33897; MGC57262; Protein stasimon; stasimon; TM41B; TMEM41B; Transmembrane protein 41B\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 22\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799853715625,"sku":"68071S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-68071s","provider":"Iright","version":"1.0","type":"link"}
