Protein attributes

Sequence length	566 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	May function as a growth and differentiation factor involved in neuritogenesis. May induce ERBB3 activation. Ref.5
Subunit structure	Binds TNR and probably TNC By similarity. Interacts with ERBB3 and GOPC.
Subcellular location	Cell membrane; Single-pass type I membrane protein By similarity. Endoplasmic reticulum membrane; Single-pass type I membrane protein By similarity. Golgi apparatus membrane; Single-pass type I membrane protein By similarity. Note: In neurons, localizes to synaptic junctions By similarity. Also detected in the endoplasmic reticulum and the Golgi By similarity. Partially enriched in lipid rafts By similarity.
Tissue specificity	Restricted to brain (at protein level). Ref.1
Developmental stage	Expressed in brain of 3 months, 5 and 10-year-old individuals. Ref.1
Post-translational modification	N-glycosylated By similarity. O-glycosylated; contains chondroitin sulfate glycans. Part-time proteoglycan, expressed in part as a proteoglycan exhibiting chondroitin sulfate glycans and in part as a non-proteoglycan form. The relative amount of both forms depends on tissues and tissues maturation By similarity. Phosphorylated; in intracellular and extracellular parts By similarity.
Miscellaneous	Different forms of various molecular weight have been observed. Such forms are possibly due to different levels of glycosylation, phosphorylation and/or protein cleavage By similarity.
Sequence similarities	Contains 1 EGF-like domain.
