Enables molecular carrier activity and retinol binding activity. Involved in several processes, including embryonic morphogenesis; heart development; and reproductive structure development. Acts upstream of or within several processes, including detection of light stimulus involved in visual percept
ion; retinoid metabolic process; and terpenoid transport. Located in extracellular space. Is active in extracellular region. Is expressed in several structures, including adipose tissue; brain; genitourinary system; gut; and hindlimb. Human ortholog(s) of this gene implicated in coronary artery disease and type 2 diabetes mellitus. Orthologous to human RBP4 (retinol binding protein 4).

Predicted to enable translation initiation factor binding activity. Predicted to be involved in transcription initiation at RNA polymerase II promoter. Predicted to be located in cytosol and nuclear speck. Predicted to be part of RNA polymerase II, core complex. Is expressed in several structures, i
ncluding alimentary system; brain; cranium; heart; and respiratory system. Orthologous to human POLR2D (RNA polymerase II subunit D). [provided by Alliance of Genome Resources, Jul 2025]
Predicted to enable retinol transmembrane transporter activity and signaling receptor activity. Acts upstream of or within establishment of localization in cell; retinol transport; and vitamin A import into cell. Located in plasma membrane. Is expressed in Harderian gland; genitourinary system; gut;
