Protein attributes

Sequence length	1537 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	May be involved in the organization of synaptic cell-cell contacts. Ref.1
Subunit structure	Interacts with CAMKII, CNKSR2 and DLG4 By similarity. Interacts with CTNND2/Catenin delta-2. Forms a complex with N-cadherin through CTNND2. Ref.1
Subcellular location	Cytoplasm Ref.1.
Tissue specificity	Brain-specific. Isoform 3 is ubiquitously expressed. Ref.2
Sequence similarities	Belongs to the LAP (LRR and PDZ) protein family. Contains 18 LRR (leucine-rich) repeats. Contains 1 PDZ (DHR) domain.
Sequence caution	The sequence BAA92603.1 differs from that shown. Reason: Frameshift at position 665.
