MTSS1 (P549) Antibody detects endogenous levels of total MTSS1 protein.

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to amino acids surrounding Pro549 of human MTSS1. Antibodies are purified by peptide affinity chromatography.

Metastasis suppressor 1 (MTSS1) is a multi-functional scaffold protein that was initially discovered using a differential display technique that identified proteins missing from bladder cancer cell lines (1,2). MTSS1 (also known as Missing in Metastasis or MIM) is a cytoskeletal remodeling protein that contains a C-terminal WH2 actin-binding motif (1,3). Presence of an IMD (IRSp53/MIM homology) domain allows MTSS1 to induce F-actin bundling and filopodia formation in cells (4). MTSS1 binds to and activates Rac, a protein known to promote the formation of filopodia and lamellipodia (5). The receptor tyrosine phosphatase δ (PTPRD) is associated with MTSS1 and is required for MTSS1-dependent cytoskeletal change (6,7). MTSS1 is a SHH responsive gene that can help regulate GLI-dependent transcriptional activity (8).
