| Protein names | Recommended name: Protein piccolo Alternative name(s): Aczonin Brain-derived HLMN protein Multidomain presynaptic cytomatrix 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 | 5068 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | May act as a scaffolding protein involved in the organization of synaptic active zones and in synaptic vesicle trafficking. Ref.1 |
| Subunit structure | |
| Subcellular location | Cell junction › synapse. Note: Concentrated at the presynaptic side of synaptic junctions. Ref.1 |
| Tissue specificity | Highly expressed in brain. Moderately expressed in pituitary gland and pancreatic islets. Low levels found in stomach. Ref.1 Ref.3 |
| Domain | C2 domain 1 is involved in binding calcium and phospholipids. Calcium binds with low affinity but with high specificity and induces a large conformational change. UniProtKB Q9JKS6 |
| Sequence similarities | Contains 2 C2 domains. Contains 1 PDZ (DHR) domain. |
| Sequence caution | The sequence BAC53723.1 differs from that shown. Reason: Unlikely isoform. Several sequence problems. The sequence BAC53724.1 differs from that shown. Reason: Unlikely isoform. Several sequence problems. The sequence CAB60731.2 differs from that shown. Reason: Probable cloning artifact. The sequence CAB60732.2 differs from that shown. Reason: Probable cloning artifact. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q9QYX7-1) Also known as: L; 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: Q9QYX7-2) Also known as: S; The sequence of this isoform differs from the canonical sequence as follows: 4859-4863: TKPTN → SKRRK 4864-5068: Missing. |
