CRABP1

A gene on chromosome 15q24 that encodes a member of the retinoic acid-binding protein family thought to play a central role in retinoic acid-mediated differentiation and proliferation.

Effects of Manipulation of CRABP1 Expression on p75NTR Expression and Fenretinide Efficacy in Neuroblastoid Human Neuroblastoma Cell Lines.
Induction of expression of CRABP1 in SH-SY5Y cells did not alter expression of p75NTR (Figure 5).
CRABP1 binds to retinoids and thereby sequesters them in the cytoplasm and prevents their shuttling to the nucleus.
Our results demonstrate neuroblastoma cell line-dependence of the effects of manipulation of p75NTR expression on CRABP1 expression and the effects of CRABP1 expression on fenretinide-induced cell death.
The fact that p75NTR and CRABP1 expression differentially affect one another and the impact of treatment with fenretinide in different neuroblastomas makes p75NTR or CRABP1, at best, complex biomarkers for likely responsiveness to that drug.
