Function

Involved in induction of the epithelial to mesenchymal transition (EMT), formation and maintenance of embryonic mesoderm, growth arrest, survival and cell migration (PubMed:10655587, PubMed:15647282, PubMed:20389281, PubMed:20562920, PubMed:21952048, PubMed:25827072). Binds to 3 E-boxes of the E-cadherin/CDH1 gene promoter and to the promoters of CLDN7 and KRT8 and, in association with histone demethylase KDM1A which it recruits to the promoters, causes a decrease in dimethylated H3K4 levels and represses transcription (PubMed:10655587, PubMed:20389281, PubMed:20562920). The N-terminal SNAG domain competes with histone H3 for the same binding site on the histone demethylase complex formed by KDM1A and RCOR1, and thereby inhibits demethylation of histone H3 at 'Lys-4' (in vitro) (PubMed:20389281, PubMed:21300290, PubMed:23721412). During EMT, involved with LOXL2 in negatively regulating pericentromeric heterochromatin transcription (PubMed:16096638). SNAI1 recruits LOXL2 to pericentromeric regions to oxidize histone H3 and repress transcription which leads to release of heterochromatin component CBX5/HP1A, enabling chromatin reorganization and acquisition of mesenchymal traits (By similarity). Associates with EGR1 and SP1 to mediate tetradecanoyl phorbol acetate (TPA)-induced up-regulation of CDKN2B, possibly by binding to the CDKN2B promoter region 5'-TCACA-3 (PubMed:20121949). In addition, may also activate the CDKN2B promoter by itself (PubMed:20121949).

Activity summary

SNAIL also known as SNAI1 is a zinc finger transcription factor involved in the regulation of cellular processes. The SNAIL protein has a mass of approximately 29 kDa and is robustly expressed in various tissues including embryonic tissues and cancerous cells. The protein functions as a repressor of transcription influencing the expression of genes associated with cellular adhesion and movement. Due to its integral role SNAIL is involved in complex regulatory networks that control cell fate and differentiation.

Biological function summary

SNAIL contributes to the epithelial-mesenchymal transition (EMT) a process critical for embryogenesis and tumor progression. It forms a part of a complex network of transcription factors that regulate cell-cell adhesion molecules like E-cadherin. SNAIL's ability to bind to specific DNA sequences allows it to suppress or activate the transcription of target genes promoting cellular metamorphosis and enabling cells to acquire motility and invade other tissues.

Pathways

SNAIL operates significantly within the TGF-beta and Wnt signaling pathways. The TGF-beta pathway enhances the expression of SNAIL which in turn represses genes that maintain the epithelial phenotype. The Wnt pathway also modulates SNAIL activity connecting it with proteins such as beta-catenin to drive EMT. These pathways highlight SNAIL's involvement in sophisticated signaling pathways that determine cell behavior adaptation and tissue remodeling.

Associated diseases and disorders

Overexpression of SNAIL associates with cancer progression particularly in metastasis due to its role in EMT. It connects with proteins like Slug and ZEB1 in this context enhancing the invasive capabilities of cancer cells. Moreover SNAIL is implicated in fibrotic diseases where excessive tissue scarring occurs. In such conditions TGF-beta-mediated activation of SNAIL contributes to abnormal tissue remodeling and fibrosis. The involvement of SNAIL in these diseases marks it as a potential target for therapeutic intervention.

In Western blot, ab216347 was shown to bind specifically to SNAIL. A band was observed at 33 kDa in wild-type HeLa cell lysates with no signal observed at this size in SNAI1 knockout cell line Human SNAI1 (SNAIL) knockout HeLa cell line ab265963 (knockout cell lysate Human SNAI1 (SNAIL) knockout HeLa cell lysate ab257692). The band observed in the knockout lysate lane below 33 kDa is likely to represent a truncated form of SNAIL. This has not been investigated further and the functional properties of the gene product have not been determined. To generate this image, wild-type and SNAI1 knockout HeLa cell lysates were analysed.First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged.
