Protein attributes

Sequence length	618 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	Inhibits primary neurogenesis. May be required to divert neurons along a specific differentiation pathway. Plays a role in the formation of somite boundaries during segmentation of the paraxial mesoderm By similarity.
Subunit structure	Can bind and activate Notch-1 or another Notch receptor By similarity.
Subcellular location	Membrane; Single-pass type I membrane protein Probable.
Domain	The DSL domain is required for binding to the Notch receptor.
Post-translational modification	Ubiquitinated by MIB (MIB1 or MIB2), leading to its endocytosis and subsequent degradation By similarity.
Involvement in disease	Spondylocostal dysostosis 1 (SCDO1) [MIM:277300]: An autosomal recessive condition of variable severity associated with vertebral and rib segmentation defects. The main skeletal malformations include fusion of vertebrae, hemivertebrae, fusion of certain ribs, and other rib malformations. Deformity of the chest and spine (severe scoliosis, kyphoscoliosis and lordosis) is a natural consequence of the malformation and leads to a dwarf-like appearance. As the thorax is small, infants frequently have respiratory insufficiency and repeated respiratory infections resulting in life-threatening complications in the first year of life. Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.1
Sequence similarities	Contains 1 DSL domain. Contains 6 EGF-like domains.
