Protein Domain
Type: Family
Description: Adenomatous polyposis coli protein 2 (APC2) promotes rapid degradation of CTNNB1 (beta-catenin) and may function as a tumor suppressor. It may function in Wnt signaling [, , ].
Protein Domain
Type: Domain
Description: This region at the C terminus of the APC proteins binds the microtubule-associating protein EB-1 []. At the C terminus of the alignment is also a PDZ-binding domain. A short motif in the middle of the region appears to be found in the APC2 proteins (e.g. ).

Type: Conserved_site
Description: Cullins are a family of hydrophobic proteins that act as scaffolds for ubiquitin ligases (E3). Cullins are found throughout eukaryotes. Humans express seven cullins (Cul1, 2, 3, 4A, 4B, 5 and 7), each forming part of a multi-subunit ubiquitin complex. Cullin-RING ubiquitin ligases (CRLs), such as Cul1 (SCF) [], play an essential role in targeting proteins for ubiquitin-mediated destruction; as such, they are diverse in terms of composition and function, regulating many different processes from glucose sensing and DNA replication to limb patterning and circadian rhythms. The catalytic core of CRLs consists of a RING protein and a cullin family member. For Cul1, the C-terminal cullin-homology domain binds the RING protein. The RING protein appears to function as a docking site for ubiquitin-conjugating enzymes (E2s). Other proteins contain a cullin-homology domain, such as the APC2 subunit of the anaphase-promoting complex/cyclosome and the p53 cytoplasmic anchor PARC; both APC2 and PARC have ubiquitin ligase activity. The N-terminal region of cullins is more variable, and is used to interact with specific adaptor proteins [, , ].This entry represents a conserved site found in various cullin proteins.

The N-terminal region of cullins is more variable, and is used to interact with specific adaptor proteins [, , ].This superfamily represents the N-terminal cullin repeat-containing domain; these repeats form a domain with a multi-helical 2-layered alpha/alpha structure, which in turn is folded into a right-handed superhelix. A similar structural domain is found in exocyst complex components such as EXO70 and EXO84.

Description: Adenomatous polyposis coli (APC) is a tumor suppressor protein that induces thedegradation of oncogenic beta-catenin and negatively regulates Wnt signalling []. It has roles in regulating cell migration, DNA replication/repair, mitosis and apoptosis [, ]. APC regulates cell-cell adhesion and cell migration through activating the APC-stimulated guanine nucleotide-exchange factor (GEF; Asef) [, ]. It acts as a mediator of ERBB2-dependent stabilisation of microtubules at the cell cortex []. It is requiredfor the localisation of MACF1/ACF7 to the cell membrane and this localisation of MACF1/ACF7 is critical for its function in microtubule stabilisation []. APC mutations are particularly prevalent in colorectal cancer [].The adenomatous polyposis coli protein family also includes APC2 [, ]and APC-related protein 1 [].
