Folate Transporter (FOLT, RFC, Reduced Folate Carrier)

A sodium-dependent transport system is responsible for transfer and distribution of vitamins to different parts of the body, the transfer includes vitamins like pantothenate, biotin, and ascorbic acid etc, These transporters belong to Solute Carrier family (SLC). Since vitamins are required for essential metabolic processes in all mammalian cells, such cells have developed intrinsic mechanisms to active accumulation of essential vitamins. Thus transporters help these cells to fulfill their requirement, they include Sodium-dependent Multi-Vitamin Transporter (SMVT), Sodium-dependent Vitamin-C Transporter (SVCT) 1 & 2, Creatine Transporter (CRT1/ CT1). The other vitamin transporters from SLC family include Thiamine Transporter Protein 1 (THTR1), Folate Transporter or Reduced Folate Carrier 1 (RFC1), Thyroid Iodide Transporter (TIT) and Taurine Transporter (TAU) etc. Folate Transporter/ FOLT/ RFC, a 512aa each protein in mouse and rat, 591aa in human (chrm 21q22.3, gene SLC19A1) transports folate compounds into mammalian cells via receptor mediated or carrier mediated mechanisms, as such maintains the intracellular concentration of folate. It shows 65% identity to mouse and hamster folate transporters. Applications: Suitable for use in ELISA and Western Blot. Other applications not tested. Recommended Dilution: ELISA: 0.5-1ug/ml.
