Gene: SMARCB1 (SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily b, member 1) Homo sapiens
Symbol: SMARCB1
Name: SWI/SNF related, matrix associated, actin dependent regulator of chromatin, subfamily b, member 1
Description: Exhibits several functions, including RNA polymerase I core promoter sequence-specific DNA binding activity; Tat protein binding activity; and p53 binding activity. Contributes to RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and nucleosomal DNA binding activity. Involved in several processes, including chromatin organization; regulation of histone modification; and regulation of transcription, DNA-templated. Localizes to SWI/SNF complex; fibrillar center; and nucleoplasm. Implicated in Coffin-Siris syndrome 3; atypical teratoid rhabdoid tumor; neurilemmomatosis; and rhabdoid cancer.
Type: protein-coding
RefSeq Status: REVIEWED
