Adenomatous Polyposis Coli Protein; Protein Apc; Deleted In Polyposis 2.5

Uniprot ID: FBLN1_HUMAN ; Reactome: R-HSA-111465 ; Gene ID: 324

Tissue Specificity: Expressed in a variety of tissues: brain, small intestine, colon, thymus, skeletal muscle, heart, prostate, lung, spleen, ovary, testis kidney, placenta, blood and liver. Isoform 1A: Very strongly expressed in brain but has relatively low expression levels in other tissues. Isoform 1B: Predominant form in all tissues except for brain, including gastric mucosa and blood.

Function: Tumor suppressor. Promotes rapid degradation of CTNNB1 and participates in Wnt signaling as a negative regulator. APC activity is correlated with its phosphorylation state. Activates the GEF activity of SPATA13 and ARHGEF4. Plays a role in hepatocyte growth factor (HGF)-induced cell migration. Required for MMP9 up-regulation via the JNK signaling pathway in colorectal tumor cells. Acts as a mediator of ERBB2-dependent stabilization of microtubules at the cell cortex. It is required for the localization of MACF1 to the cell membrane and this localization of MACF1 is critical for its function in microtubule stabilization.
