Supplementary information

Cellular Retinoic Acid-Binding Protein 2 (CRABP2) mechanically facilitates cellular retinoic acid (RA) signaling by transporting RA to the nucleus. The protein is also known as CRABP II and is approximately 15 kDa in mass. You can find its expression in various tissues including skin adipose tissue and brain where it exhibits specific roles in RA signaling and cellular differentiation processes.
Biological function summary

CRABP2 participates in modulating the availability of RA which influences gene expression by binding to nuclear receptors. Although CRABP2 functions independently rather than as part of a larger protein complex it holds a significant role in gene transcription regulation. This active role in regulating RA levels impacts cellular differentiation and proliferation processes essential for tissue development and homeostasis.

Pathways

CRABP2 is an important participant in the retinoic acid signaling pathway. This pathway impacts important biological processes such as embryonic development and cell growth. CRABP2 closely interacts with the retinoic acid receptor (RAR) guiding RA to RARs and contributing to the regulation of gene expression. Moreover it is linked to the transforming growth factor-beta (TGF-beta) pathway playing a role in managing cellular apoptosis and differentiation.

Researchers associate CRABP2 with several cancers notably skin cancer due to its influence on cell proliferation. Altered expression or function of CRABP2 can also affect neurodegenerative diseases impacting pathways involving neuronal survival. CRABP2's interactions with proteins like RAR and in cancer contexts with overexpressed RA receptors highlight its relevance in modulating RA-dependent processes that can lead to pathological states.
