Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Species predicted to react based on 100% sequence homology: Monkey.
Specificity / Sensitivity
LASP1 Antibody detects endogeneous levels of total LASP1 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala191 of human LASP1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
LASP1 is a cytoskeletal scaffold protein belonging to the LIM protein subfamily (1,2). LASP1 consists of an N-terminal LIM domain, followed by two nebulin repeats, and a C-terminal SH3 domain (1,3). The nebulin repeats interact with actin, while the SH3 domain interacts with palladin (4,5), suggesting LASP1 functions as an actin-binding protein, possibly in cytoskeletal organization. LASP1 has been shown to localize to focal adhesions, lamellipodia, and membrane ruffles (6-8) and might be involved in membrane migration. Overexpression of LASP1 has been associated with metastatic cancers, such as breast and ovarian cancer (2). In these cases, membrane, cytoplasmic, and nuclear localization of LASP1 in the tumor cell has been reported, suggesting LASP1 involvement in membrane and nuclear signaling (9,10).
