Functions
drug binding / folic acid binding / folic acid transporter activity / methotrexate binding / receptor activity
Processes
anterior neural tube closure / axon regeneration / cardiac neural crest cell migration involved in outflow tract morphogenesis / cellular protein metabolic process / cellular response to folic acid / COPII vesicle coating / ER to Golgi vesicle-mediated transport / folic acid metabolic process / folic acid transport / heart looping / membrane organization / neural crest cell migration involved in heart formation / pharyngeal arch artery morphogenesis / post-translational protein modification / protein N-linked glycosylation via asparagine / receptor-mediated endocytosis / regulation of canonical Wnt signaling pathway / regulation of transforming growth factor beta receptor signaling pathway
Components
anchored component of external side of plasma membrane / apical plasma membrane / basolateral plasma membrane / cell surface / clathrin-coated vesicle / endoplasmic reticulum membrane / endoplasmic reticulum-Golgi intermediate compartment membrane / endosome / ER to Golgi transport vesicle membrane / extracellular exosome / Golgi membrane / integral component of plasma membrane / membrane / nucleus / plasma membrane
General Function
Receptor activity
Specific Function
Binds to folate and reduced folic acid derivatives and mediates delivery of 5-methyltetrahydrofolate and folate analogs into the interior of cells. Has high affinity for folate and folic acid analogs at neutral pH. Exposure to slightly acidic pH after receptor endocytosis triggers a conformation change that strongly reduces its affinity for folates and mediates their release. Required for normal embryonic development and normal cell proliferation.
