Recombinant Human Retinaldehyde-binding protein 1 (RLBP1)

Uniprot Id

P12271

Target Species

Human

Target Name

RLBP1

Target Full Name

Retinaldehyde-binding protein 1

Target Function

Soluble retinoid carrier essential the proper function of both rod and cone photoreceptors. Participates in the regeneration of active 11-cis-retinol and 11-cis-retinaldehyde, from the inactive 11-trans products of the rhodopsin photocycle and in the de novo synthesis of these retinoids from 11-trans metabolic precursors. The cycling of retinoids between photoreceptor and adjacent pigment epithelium cells is known as the 'visual cycle'.

Target Involvement

Bothnia retinal dystrophy (BRD); Rod-cone dystrophy Newfoundland (NFRCD); Retinitis punctata albescens (RPA)

Target Subcellular Location

Cytoplasm.

Target Tissue Specificity

Retina and pineal gland. Not present in photoreceptor cells but is expressed abundantly in the adjacent retinal pigment epithelium (RPE) and in the Mueller glial cells of the retina.

Target Research Area

Others

Target Synonyms

Cellular retinaldehyde binding protein 1; Cellular retinaldehyde binding protein; Cellular retinaldehyde-binding protein; MGC3663; Retinaldehyde binding protein 1; Retinaldehyde-binding protein 1; RLBP 1; RLBP1; RLBP1_HUMAN

Target Background

The protein encoded by this gene is a 36-kD water-soluble protein which carries 11-cis-retinaldehyde or 11-cis-retinal as physiologic ligands. It may be a functional component of the visual cycle. Mutations of this gene have been associated with severe rod-cone dystrophy, Bothnia dystrophy (nonsyndromic autosomal recessive retinitis pigmentosa) and retinitis punctata albescens.
