SUBCELLULAR LOCALIZATION	extracellular

	intracellular,cytoplasm,organelle,endoplasmic reticulum
text	OLFM1 staining was equally strong in the endoplasmic reticulum and the growth cones

basic FUNCTION	playing a role in regulating the production of neural crest by the neural tube
	participates in neural progenitor maintenance, cell death in brain, and optic nerve arborization
	localization of OLFM1 in the growth cones of neuronal cells suggests that it may play a role in axon growth and/or guidance
	OLFM1 is a component of neuronal growth cones and is a novel soluble ligand of RTN4R, which regulates axonal outgrowth and axon bundle formation during brain development
	is a highly expressed neuronal glycoprotein important for nervous system development
	potential role for OLFM1 in clustering receptors to regulate signaling and sheds light on the conformation of several other olfactomedin domain family members

small molecule

protein	OLFM1 is a novel RTN4R ligand that modulates the functions of the RTN4R complex in axonal growth
	binding of RTN4R and LINGO1 was similarly inhibited by OLFM1 coexpression
	is an endogenous antagonist of myelin-associated axon growth inhibitors

	System Type Disorder Pubmed neurology acquired   application of OLFM1 or stimulation of its expression may be used to facilitate neuronal growth after axonal damage or injury cancer digestive colon may be a valuable therapeutic target for Colorectal cancer patients

ANIMAL & CELL MODELS

	Olfm1(-/-) female mice were previously reported to have reduced fertility
	olfactory system was both structurally and functionally disturbed by the mutation in the Olfm1 gene which may contribute to the neonatal death and loss of body weight of Olfm1 mutant
