Description

General description

Rabbit anti-14-3-3 Sigma or stratifin is mapped to human chromosome 1p36.11. 14-3-3σ protein is expressed as seven isoforms and has molecular weight in the range of 25 to 30 kDa. It is an acidic homodimeric protein and harbors pleckstrin homology (PH) domain. 14-3-3σ is highly expressed in epidermis.

Immunogen

The epitope recognized by PLA0201 maps to a region between residue 198 and 248 of human 14-3-3 sigma using the numbering given in entry NP_006133.1 (GeneID 2810).

Application

Rabbit anti-14-3-3 Sigma Antibody, Affinity Purified has been used in the pull down assay for Rho associated coiled-coil containing protein kinase 1 (ROCK1) proteins and heat shock 70 kDa 4 protein (Hsp74) in HCT116 cancer cells.

Biochem/physiol Actions

Rabbit anti-14-3-3 or stratifin participates in several biological events including apoptosis and cell differentiation. It regulates the transcription matrix metallopeptidases (MMPs) in fibroblasts and may serve as therapeutic potential in wound healing. 14-3-3σ is less expressed and is hyper methylated in breast cancer cells. It plays a key role in linking signalling proteins and in the enhancing of protein kinase C functionality. A mutation in the stratifin gene is implicated in epilation phenotype in mice. It interacts with ubiquitin-specific protease 8 (USP8) and is highly expressed in human lung adenocarcinoma.

Physical form

Tris-citrate/phosphate buffer, pH 7 to 8 containing 0.09% Sodium Azide

Other Notes

14-3-3 sigma was identified as an epithelial cell marker. It is part of the 14-3-3 family of proteins in which seven isoforms have been identified: beta, zeta, gamma, eta, epsilon, tau, and sigma. 14-3-3 proteins function as adaptors that bind with a number of partners to mediate various signaling pathways. 14-3-3 sigma is also called stratifin or HME1 and appears to function as a tumor suppressor whose expression can be downregulated via methylation. Loss of 14-3-3 sigma expression results in a defective G2/M phase checkpoint and appears to contribute to both epithelial and non-epithelial tumorigenesis.
