SNF5, or SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily b, member 1, is a human gene encoded by SMARCB1. It may also be known as: SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily B member 1; BAF47; Integrase interactor 1 protein homolog; hSNF5; BRG1-associated factor 47; sucrose nonfermenting, yeast, homolog-like 1; integrase interactor 1; malignant rhabdoid tumor suppressor; protein phosphatase 1, regulatory subunit 144; INI1; MRD15; PPP1R144; RDT; RTPS1L1; SWNTS1; Sfh1p; Snr1; hSNFS. The encoded protein has an amino acid length of 385 and a mass of 44.1 kDa. SNF5 is a member of the SNF5 family. Homologs of this gene exist in other organisms, including: Mouse, Frog.
