Product Description |
Recombinant Biotinylated Human Latent TGF beta 1/TGFB1 Protein is expressed from HEK293 with His tag and Avi tag at the N-Terminus.It contains Leu30-Ser390(C33S). |
Product Background |
Latent TGF beta 1 cDNA encodes a 390 amino acid precursor that contains a 29 aa signal peptide and a 361 aa proprotein. A furin‑like convertase processes the proprotein to generate an N‑terminal 249 aa latency‑associated peptide (LAP) and a C‑terminal 112 aa mature TGF‑ beta 1. Disulfide‑linked homodimers of LAP and TGF‑ beta 1 remain non‑covalently associated after secretion, forming the small latent TGF‑ beta 1 complex. |
