  • 产品描述：

    The recombinant Human SLC4A1 protein is encoded by the gene of SLC4A1 (1-403aa). The gene of SLC4A1 was cloned in a system (E.coli) that supported the expression of SLC4A1. Modification of SLC4A1 by recombinant DNA technology could lead to the expression of the target protein. The protein was fused with N-terminal 10xHis tag & C-terminal Myc tag in the production. The purity is 90% determined by SDS-PAGE.

    SLC4A1 is a protein coding gene that encodes Band 3 anion transport protein (Solute carrier family 4 member 1). According to some studies, SLC4A1 may have the following features.
    The enhancer RNA lnc-SLC4A1-1 can apparently regulate unexplained recurrent pregnancy loss (URPL) by activating the CXCL8 and NF-kB pathways. A novel compound heterozygous SLC4A1 mutation in patients with autosomal recessive distal renal tubular acidosis in Thailand. The activity and distribution of carbonic anhydrase II in cells and its effect on the transport activity of anion exchanger AE1/SLC4A1. The molecular mechanism of autosomal dominant and recessive distal renal tubular acidosis caused by mutation of SLC4A1 (AE1). Two new SLC4A1 gene mutations were found in two unrelated Chinese families with distal renal tubular acidosis. A new variant of SLC4A1 in a family of autosomal dominant distal renal tubular acidosis with a severe phenotype.

  • 功能：
    Functions both as a transporter that mediates electroneutral anion exchange across the cell membrane and as a structural protein. Major integral membrane glycoprotein of the erythrocyte membrane; required for normal flexibility and stability of the erythrocyte membrane and for normal erythrocyte shape via the interactions of its cytoplasmic domain with cytoskeletal proteins, glycolytic enzymes, and hemoglobin. Functions as a transporter that mediates the 1:1 exchange of inorganic anions across the erythrocyte membrane. Mediates chloride-bicarbonate exchange in the kidney, and is required for normal acidification of the urine.

This resets the equilibrium, such that kAE1 R901X resides predominantly in an endomembrane compartment, thereby likely participating in development of dRTA disease. PMID: 26984737
