General annotation (Comments)

Function

Induces KLC1 association with vesicles and functions as a cargo in axonal anterograde transport. Complex formation with APBA2 and APP, stabilizes APP metabolism and enhances APBA2-mediated suppression of beta-APP40 secretion, due to the retardation of intracellular APP maturation. In complex with APBA2 and C99, a C-terminal APP fragment, abolishes C99 interaction with PSEN1 and thus APP C99 cleavage by gamma-secretase, most probably through stabilization of the direct interaction between APBA2 and APP. The intracellular fragment AlcICD suppresses APBB1-dependent transactivation stimulated by APP C-terminal intracellular fragment (AICD), most probably by competing with AICD for APBB1-binding. May modulate calcium-mediated postsynaptic signals By similarity. Ref.1

Subunit structure

Directly interacts with APBA2. Forms a tripartite complex with APBA2 and APP. The CTF1 chain interacts with PSEN1. The intracellular fragment AlcICD interacts with APBB1; this interaction stabilizes AlcICD metabolism. Interacts with KLC1 and APBB1 By similarity. Ref.1 Ref.8

Subcellular location

Endoplasmic reticulum membrane; Single-pass type I membrane protein. Golgi apparatus membrane. Cell projection. Cell junctionsynapsepostsynaptic cell membrane; Single-pass type I membrane protein By similarity. Nucleus. Note: Neurite tips. Localized in the postsynaptic membrane of both excitatory and inhibitory synapses By similarity. The AlcICD fragment is translocated to the nucleus upon interaction with APBB1. Ref.8

Tissue specificity

Expressed in the brain and, a lower level, in the heart, skeletal muscle, kidney and placenta. Accumulates in dystrophic neurites around the amyloid core of Alzheimer disease senile plaques (at protein level). Ref.1 Ref.7

Domain

The cytoplasmic domain is involved in interaction with APBA2, as well as the binding of synaptic Ca2+ By similarity.

Post-translational modification

Proteolytically processed under normal cellular conditions. A primary zeta-cleavage generates a large extracellular (soluble) N-terminal domain (sAlc) and a short C-terminal transmembrane fragment (CTF1). A secondary cleavage catalyzed by presenilin gamma-secretase within the transmembrane domain releases the beta-Alc-alpha chain in the extracellular milieu and produces an intracellular fragment (AlcICD). This processing is strongly suppressed in the tripartite complex formed with APBA2 and APP, which seems to prevent the association with PSEN1.

Sequence similarities

Contains 2 cadherin domains.

Sequence caution

The sequence BAA74934.2 differs from that shown. Reason: Erroneous initiation.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
