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 mam-mals 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 kidney, colon and small intestine (1-3).
L-plastin (plastin-2) or LCP1 (lymphocyte cytosolic protein 1) is mainly expressed in he-matopoietic cells and nonhematopoietic tumors, including increased expression correlated with metastatic progression in colon cancer cell lines (4).
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/co-receptor complex (TCR/CD3) in association with the CD2 cell adhesion molecule or the CD28 receptor (6).
Phosphorylation at Ser5 increases LCP1 ability to bind F-actin and increase cell motility (7,8).
