SMARCB1, switch/sucrose nonfermenting (SWI/SNF) related, matrix associated, actin dependent regulator of chromatin, subfamily b, member 1 is a core subunit of the SWI/SNF complex. It is a nuclear protein showing ubiquitous expression. SMARCB1 gene is mapped to human chromosome 22q11.23.

SMARCB1 (NP_003064, 81 a.a. ~ 180 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.
SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily b, member 1 (SMARCB1) participates in cell cycle progression and epigenetic regulation. It blocks cyclin-dependent kinase (CDK4/6) and cyclin D1 and participates in regulating the wingless (Wnt)/β-catenin signaling pathway. Mutations in the SMARCB1 gene is implicated with severe neurodevelopmental deficits, central nervous system (CNS) structural abnormalities, and seizures. It is associated with the pathophysiology of rare congenital malformation namely, Coffin-Siris syndrome (CSS). Loss of the SMARCB1 gene is linked to the malignant rhabdoid tumor (MRT), a rare childhood cancer. Moreover, MARCB1 gene abnormalities are correlated to gastrointestinal (GI) and sino-nasal carcinoma epithelioid sarcoma (ES), and renal medullary carcinoma (RMC).

SMARCB1 is the core subunit of the SWI/sucrose non-fermenting ATP-dependent chromatin remodelling complex located on the long arm of chromosome 22 (22q11.2). Since discovering genetic alterations of the SMARCB1 gene in malignant rhabdoid tumours, the family of tumours harbouring loss

Coffin-Siris syndrome (CSS) is a rare congenital malformation syndrome, recently found to be caused by mutations in several genes encoding components of the BAF complex. To date, 109 patients have been reported with their mutations: SMARCB1 (12%), SMARCA4 (11%), SMARCE1
SMARCB1 inactivation occurs in a variety of tumors, being caused by various genetic mechanisms. Since SMARCB1 and EWSR1 genes are located close to each other on chromosome 22, larger SMARCB1 deletions may encompass the EWSR1 locus. Herein, we report four
