RBP7 protein, a member of the CRBP family, is involved in the stability and metabolism of vitamin A. It binds to all-trans-retinol but with lower affinity compared to other CRBPs. RBP7 protein is expressed in fat, spleen, and other tissues, indicating possible tissue-specific functions. RBP7 Protein, Human (His) is the recombinant human-derived RBP7 protein, expressed by E. coli , with N-6*His labeled tag.
