Protein attributes

Sequence length	522 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	Required for depolarization-dependent survival of cultured cerebellar granule neurons. May mediate homophilic as well as heterophilic cell-cell interaction with AMIGO1 or AMIGO3. May contribute to signal transduction through its intracellular domain. May be required for tumorigenesis of a subset of gastric adenocarcinomas.
Subunit structure	Binds itself as well as AMIGO1 and AMIGO3 By similarity.
Subcellular location	Cell membrane; Single-pass type I membrane proteinBy similarity. NucleusBy similarity. Note= Associated with nucleus as well as plasma membrane. Restricted to somata of cerebellar as well as hippocampal neurons By similarity.
Tissue specificity	Highest levels in breast, ovary, cervix, and uterus. Lower levels in lung, colon, and rectum. Differentially expressed in 56% of thyroid, 57% of pancreatic and 45% of stomach cancers.
Sequence similarities	Belongs to the immunoglobulin superfamily. AMIGO family. Contains 1 Ig-like C2-type (immunoglobulin-like) domain. Contains 6 LRR (leucine-rich) repeats.
