| Protein names | Recommended name: Plakophilin-4 Alternative name(s): Armadillo-related protein | ||||
| Gene names |
| ||||
| Organism | Mus musculus (Mouse) [Reference proteome] | ||||
| Taxonomic identifier | 10090 [NCBI] | ||||
| Taxonomic lineage | Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Glires › Rodentia › Sciurognathi › Muroidea › Muridae › Murinae › Mus › Mus![]() |
Protein attributes
| Sequence length | 1190 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Plays a role as a regulator of Rho activity during cytokinesis. May play a role in junctional plaques By similarity. |
| Subunit structure | Interacts (via the C-terminus) with FRMPD2 (via the PDZ 2 domain). Interacts with PDZD2. Interacts with RHOA; the interaction is detected at the midbody. Interacts with ECT2; the interaction is detected at the midbody By similarity. |
| Subcellular location | Cell junction › desmosome By similarity. Cytoplasm › cytoskeleton › spindle By similarity. Cytoplasm › cytoskeleton › spindle pole By similarity. Midbody By similarity. Cell membrane; Peripheral membrane protein By similarity. Note: Associated with the pericentrosomal region in interphase and with spindle poles during mitosis. In anaphase, during chromosome segregation, is recruited to the central microtubule bundle, focussed at the spindle midzone and ultimately localizes to the midbody at cytokinesis. Constituent of the midbody cytoskeletal matrix. Colocalized with desmoplakin at desmosomal junctional plaques in cultured epithelial cells By similarity. |
| Sequence similarities | Belongs to the beta-catenin family. Contains 4 ARM repeats. |
| Sequence caution | The sequence BAC37187.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q68FH0-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q68FH0-2) The sequence of this isoform differs from the canonical sequence as follows: 1042-1084: Missing. | ||||||
| Isoform 3 (identifier: Q68FH0-3) The sequence of this isoform differs from the canonical sequence as follows: 1-341: Missing. 637-637: V → G 638-1190: Missing. |
