LIM Zinc Finger Domain Containing 1 (LIMS1) Antibody

Background

LIMS1, also known as PINCH1 (Particularly Interesting New Cysteine-Histidine rich protein), is a LIM domain-containing adaptor protein involved in integrin-mediated cell adhesion and signaling. LIMS1 interacts with focal adhesion proteins such as ILK (integrin-linked kinase) and acts as a scaffold to regulate cell-ECM adhesion, cytoskeletal organization, and signaling pathways like PI3K/Akt, MAPK/ERK, and TGF-β. It is broadly expressed in tissues and plays critical roles in cell survival, migration, differentiation, and embryonic development. LIMS1 is essential for cardiac and skeletal muscle development, where it stabilizes focal adhesions and modulates mechanical signaling. Dysregulation of LIMS1 is associated with cancer progression, metastasis, and fibrosis due to its role in integrin signaling and actin cytoskeleton remodeling. Knockout models show embryonic lethality, severe developmental defects, and impaired adhesion, highlighting its importance in tissue homeostasis.
