| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Actin-associated protein that may play a role in modulating actin-based shape and motility of dendritic spines and renal podocyte foot processes. Seems to be essential for the formation of spine apparatuses in spines of telencephalic neurons, which is involved in synaptic plasticity By similarity. |
| Subunit structure | Interacts with BAIAP1. Interacts with actin By similarity. Interacts (via PPxY motifs) with WWC1 (via WW domains). Ref.8 Ref.11 |
| Subcellular location | Cytoplasm › cytoskeleton By similarity. Cell junction › tight junction By similarity. Perikaryon By similarity. Cell projection › dendritic spine By similarity. Cell junction › synapse › postsynaptic cell membrane › postsynaptic density By similarity. Cell junction › synapse By similarity. Note: Localized at the tight junction of cells. In brain, localized to the postsynaptic densities and in the perikarya. Associated with dendritic spines of a subset of synapses By similarity. Ref.8 |
| Tissue specificity | Expressed in cerebral cortex. Ref.1 |
| Post-translational modification | O-glycosylated By similarity. Isoform 2 is phosphorylated on Ser-826, Thr-836, Ser-840 and Ser-871. |
| Sequence similarities | Belongs to the synaptopodin family. |
| Sequence caution | The sequence BAA82981.2 differs from that shown. Reason: Erroneous initiation. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q8N3V7-1) 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: Q8N3V7-2) The sequence of this isoform differs from the canonical sequence as follows: 1-244: Missing. 921-929: VWKPSFCFK → DRRESLPTSP...SLPAEASCTT | ||||||
| Note: Contains a phosphoserine at position 871. Contains a phosphoserine at position 826. Contains a phosphoserine at position 894. Contains a phosphoserine at position 854. | ||||||
| Isoform 3 (identifier: Q8N3V7-3) The sequence of this isoform differs from the canonical sequence as follows: 1-244: Missing. |
