Gene Information

human ... CRABP2(1382)

General description

A number of specific carrier proteins for members of the vitamin A family have been discovered. Cellular retinoic acid binding proteins (CRABP) are low molecular weight proteins whose precise function remains unknown. The inducibility of the CRABP2 gene suggests that this isoform is important in retinoic acid-mediated regulation of human skin growth and differentiation. It has been postulated that the CRABP2 gene is transcriptionally regulated by a newly synthesized regulatory protein. (provided by RefSeq)

Application

Biochem/physiol Actions

Cellular retinoic acid binding protein 2 (CRABP2) plays a crucial role in acceleration of the transcriptional activity. In the nucleus, by binding directly to the nuclear receptor RAR, it forms a complex for connecting retinoic acid (RA) from the binding protein to the receptor. This interaction finally helps to accelerate the transcriptional activity. It may have impact in the immature phenotype in glioma cells.

Impairment of endogenous differentiation pathways like retinoic acid (RA) signaling seems to be a central pathogenetic event in astrocytic gliomas. Among others, expression of the differentiation-promoting RA chaperon protein cellular retinoic acid binding protein 2 (CRABP2) is extenuated in high-grade

Cellular retinoic acid-binding protein II (CRABP-II) undergoes nuclear translocation upon binding of retinoic acid (RA). In the nucleus, CRABP-II directly binds to the nuclear receptor RAR to form a complex through which RA is "channeled" from the binding protein to
