Product Overview
Tag | His |
Host Species | Human |
Accession | NP_009016.1 |
Synonym | FRP, FSL1, MIR198 |
Background | Follistatin-related protein 1 (FSTL1) is an extracellular glycoprotein whose functional significance in physiological and pathological processes is incompletely understood. Recently, we have shown that FSTL1 acts as a muscle-derived secreted factor that is up-regulated by Akt activation and ischemic stress and that FSTL1 exerts favorable actions on the heart and vasculature. Here, we sought to identify the receptor that mediates the cellular actions of FSTL1. It contains an FS module, a follistatin-like sequence containing 1 conserved cysteine residues. FSTL1 is thought to be an autoantigen associated with rheumatoid arthritis. DIP2A functions as a novel receptor that mediates the cardiovascular protective effects of FSTL1. Experiment results have provided in vivo and in vitro evidence to demonstrate that Fstl1 modulates lung development and alveolar maturation, in part, through BMP4 signaling. |
Description | A DNA sequence encoding the human FSTL1 (NP_009016.1) precursor (Met 1-Ile 308) with a carboxy-terminal His tag was expressed. |
Source | HEK293 |
Predicted N Terminal | Glu 21 |
AA Sequence | Met 1-Ile 308 |
Molecular Weight | The secreted recombinant human FSTL1 consists of 299 a.a. with the predicted molecular mass of 34.2 kDa. As a result of glycosylation, rhFSTL1 migrates as an approximately 47 kDa band in SDS-PAGE under reducing conditions. |
Purity | >98% as determined by SDS-PAGE |
Endotoxin | < 1.0 EU per μg of the protein as determined by the LAL method |
Bioactivity | Please contact us for detailed information |
Formulation | Lyophilized from sterile PBS, pH 7.4. |
Stability | The recombinant proteins are stable for up to 1 year from date of receipt at -70°C. |
Usage | For Research Use Only |
Storage | Store the protein under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. |
