Anti-TAGLN/Transgelin Antibody Picoband® Fluoro647 Conjugated

Transgelin, also known as SM22 alpha, is a protein that in humans is encoded by the TAGLN gene. This gene encodes a shape change and transformation sensitive actin-binding protein which belongs to the calponin family. It is ubiquitously expressed in vascular and visceral smooth muscle, and is an early marker of smooth muscle differentiation. The encoded protein is thought to be involved in calcium-independent smooth muscle contraction. It acts as a tumor suppressor, and the loss of its expression is an early event in cell transformation and the development of some tumors, coinciding with cellular plasticity. The encoded protein has a domain architecture consisting of an N-terminal calponin homology (CH) domain and a C-terminal calponin-like (CLIK) domain. Mice with a knockout of the orthologous gene are viable and fertile but their vascular smooth muscle cells exhibit alterations in the distribution of the actin filament and changes in cytoskeletal organization.

Sodium-dependent phosphate transport protein 2B; Sodium-phosphate transport protein 2B; Na (+) -dependent phosphate cotransporter 2B; NaPi3b; Sodium/phosphate cotransporter 2B; Na (+) /Pi cotransporter 2B; NaPi-2b; Solute carrier family 34 member 2; SLC34A2

Highly expressed in lung. Also detected in pancreas, kidney, small intestine, ovary, testis, prostate and mammary gland. In lung, it is found in alveolar type II cells but not in bronchiolar epithelium.

May be involved in actively transporting phosphate into cells via Na+ cotransport. It may be the main phosphate transport protein in the intestinal brush border membrane. May have a role in the synthesis of surfactant in lungs' alveoli.
