Recombinant Human Cellular Retinoic Acid-Binding Protein 1 (CRABP-I) Fragment (residues 1-137) is a high-purity, soluble protein designed for structural and biochemical studies. This fragment captures a stable, functional domain of CRABP-I, enabling research into retinoic acid regulation and signaling pathways.

Cellular retinoic acid-binding protein 1 (CRABP-I) is a cytosolic protein that plays a key role in regulating the access of retinoic acid to nuclear retinoic acid receptors, thereby influencing gene expression and cellular differentiation. Located in the cytoplasm, CRABP-I is essential for managing retinoic acid bioavailability and signaling, making it a critical component in studies of development, homeostasis, and disease mechanisms. The provided fragment (residues 1-137) represents a computationally optimized, stable region ideal for investigating protein function and interactions.
