General description

Talin 1 (TLN1) gene mapped to human chromosome 9p13.3, codes for a 270kDa cytoskeletal protein containing 2541 amino acids. Talin-1 is widely expressed in the kidney, liver, spleen, stomach, lung and vascular smooth muscle. The TLN1 antiparallel dimeric structure is characterized with a globular head containing four-point-one, ezrin, radixin, moesin (FERM) domain and rod domain involved in dimer formation.


Reacts specifically with mammalian and avian talin. In immunoblotting, the antibody recognizes an epitope located on the 225 kDa chicken talin molecule and the 190 kDa fragment obtained by protease cleavage. It also localizes the slightly higher molecular weight talin in human platelets. The antibody labels focal adhesions, membrane ruffles, and ventral streaks in methanol/acetone fixed cultured fibroblasts.

Biochem/physiol Actions

Talin 1 (TLN1) is a cytoskeletal protein, which plays a vital role in cancer cell adhesion, migration and invasion. It is also involved in integrin activation and it facilitates the adhesion of integrin to actin cytoskeleton. TLN1 might act as a potential prognostic biomarker in nasopharyngeal carcinoma (NPC). Overexpression of TLN1 is observed in endometrioid carcinoma, oral squamous cell carcinoma (OSCC), prostate cancer and hepatocellular carcinoma. Serum TLN1 functions as a potential biomarker of hepatocellular carcinoma (HCC). Talin 1 (TLN1) is highly expressed in glioblastoma multiforme (GBM). The Inhibition of TLN1 activity helps in diminishing malignant features of GBM cells. It also plays an important role in regulation of, Bevacizumab (anti-angiogenic agent)-resistance.
