LCP1 Antibody

5350:

Western Blotting

LCP1 Antibody detects endogenous levels of total LCP1 protein.

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Asp292 of human LCP1 protein. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western blot analysis of extracts from various cell lines using LCP1 Antibody.

Highly conserved and widely expressed plastin proteins comprise a subset of actin-binding proteins that include proteins that promote actin bundling. Three plastins exhibiting differential expression are found in mammals and include L-plastin, T-plastin, and I-plastin. T-plastin (plastin-3) is found in cells of most solid tissues, while I-plastin (plastin-1) is expressed specifically in the kidney, colon, and small intestine (1-3). Research studies have shown that L-plastin (plastin-2) or lymphocyte cytosolic protein 1 (LCP1) is mainly expressed in hematopoietic cells and nonhematopoietic tumors, and increased expression correlates with metastatic progression in colon cancer cell lines (4). Investigators have found that overexpression of LCP1 in premetastatic cancer cell lines induces invasion and loss of E-cadherin expression, which is characteristic of metastatic cancer cell lines (5). LCP1 becomes phosphorylated at Ser5 upon stimulation through the T cell receptor/CD3 complex in association with the CD2 cell adhesion molecule or the CD28 receptor (6). Phosphorylation at Ser5 enhances the ability of LCP1 to bind to F-actin and increases cell motility (7,8).
