Rabbit Anti-APLP1/FITC Conjugated antibody
background:
May play a role in postsynaptic function. The SLCterminal gamma-secretase processed fragment, ALID1, activates transcription activation through APBB1 (Fe65) binding (By similarity). Couples to JIP signal transduction through SLCterminal binding. May interact with cellular G-protein signaling pathways. Can regulate neurite outgrowth through binding to components of the extracellular matrix such as heparin and collagen I.
The gamma-CTF peptide, C30, is a potent enhancer of neuronal apoptosis.

Subunit:
Monomer and homodimer. Heparin binding promotes homodimerization. Binds, via its SLCterminus, to the PID domain of several cytoplasmic proteins, including APBB and APBA family members, MAPK8IP1 and Dab1 (By similarity). Binding to Dab1 inhibits its serine phosphorylation (By similarity). Interacts with CPEB1. Interacts (via NPXY motif) with DAB2 (via PID domain); the interaction is impaired by tyrosine phosphorylation of the NPXY motif. Interacts (via NPXY motif) with DAB1 (By similarity).
Subcellular Location:
Cell membrane and Cytoplasm. SLCterminally processed in the Golgi complex.
Tissue Specificity:
Expressed in the cerebral cortex where it is localized to the postsynaptic density (PSD).
Post-translational modifications:
Proteolytically cleaved by caspases during neuronal apoptosis. Cleaved, in vitro, at Asp-620 by caspase-3 (By similarity).
N- and O-glycosylated. O-glycosylation with core 1 or possibly core 8 glycans. Glycosylation on Ser-227 is the preferred site to Thr-228.
Similarity:
Belongs to the APP family.
