Supplementary information

SNF5/SMARCB1 also known as INI1 or BAF47 is a member of the SWI/SNF chromatin remodeling complex. It acts in modifying chromatin structure to regulate gene expression. SNF5/SMARCB1 possesses a mass of approximately 47 kDa. The protein expresses ubiquitously in various tissues with notable presence in the nucleus. Through its mechanical activity in chromatin remodeling SNF5/SMARCB1 facilitates transcriptional regulation and chromosomal stability.
Biological function summary

SNF5/SMARCB1 acts as an integral component of the SWI/SNF complex. This complex functions in altering nucleosome positioning on DNA impacting gene expression linked to cell cycle regulation differentiation and DNA repair. By working within this complex SNF5/SMARCB1 helps in the activation or repression of specific gene sets based on cellular requirements displaying an essential role in maintaining normal cellular function. The interplay of SNF5/SMARCB1 with other chromatin-modifying enzymes extends its influence across various genetic pathways.

Pathways

The involvement of SNF5/SMARCB1 in the cell cycle and transcription regulation pathways is acknowledged. It participates intimately in the p53 signaling pathway which is critical for cell cycle checkpoints and apoptotic responses. SNF5/SMARCB1 engages with other proteins such as p53 and RB1 coordinating to maintain genomic integrity and proper transcriptional programming. These pathways spotlight the protein's influence in important cell fate decisions.

SNF5/SMARCB1 mutations or deletions associate closely with malignant rhabdoid tumors an aggressive pediatric cancer and schwannomatosis a disorder involving benign nerve sheath tumors. The loss of SNF5/SMARCB1 disrupts the SWI/SNF complex's function triggering unregulated cell proliferation and cancer progression. Within these disorders the SWI/SNF complex itself which contains other subunits like BRG1 and BRM is also impacted highlighting SMARCB1's critical role in tumor suppression.

Target data

Core component of the BAF (hSWI/SNF) complex. This ATP-dependent chromatin-remodeling complex plays important roles in cell proliferation and differentiation, in cellular antiviral activities and inhibition of tumor formation. The BAF complex is able to create a stable, altered form of chromatin that constrains fewer negative supercoils than normal. This change in supercoiling would be due to the conversion of up to one-half of the nucleosomes on polynucleosomal arrays into asymmetric structures, termed altosomes, each composed of 2 histones octamers. Stimulates in vitro the remodeling activity of SMARCA4/BRG1/BAF190A. Involved in activation of CSF1 promoter. Belongs to the neural progenitors-specific chromatin remodeling complex (npBAF complex) and the neuron-specific chromatin remodeling complex (nBAF complex). During neural development a switch from a stem/progenitor to a postmitotic chromatin remodeling mechanism occurs as neurons exit the cell cycle and become committed to their adult state. The transition from proliferating neural stem/progenitor cells to postmitotic neurons requires a switch in subunit composition of the npBAF and nBAF complexes. As neural progenitors exit mitosis and differentiate into neurons, npBAF complexes which contain ACTL6A/BAF53A and PHF10/BAF45A, are exchanged for homologous alternative ACTL6B/BAF53B and DPF1/BAF45B or DPF3/BAF45C subunits in neuron-specific complexes (nBAF). The npBAF complex is essential for the self-renewal/proliferative capacity of the multipotent neural stem cells. The nBAF complex along with CREST plays a role regulating the activity of genes essential for dendrite growth (By similarity). Plays a key role in cell-cycle control and causes cell cycle arrest in G0/G1.
