Protein attributes
| Sequence length | 454 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Probable early component of the autophagy machinery being involved in formation of preautophagosomal structures and their maturation into mature phagosomes in response to PtdIns3P. May bind PtdIns3P. Ref.10 |
| Subunit structure | Interacts with TECPR1. Ref.11 |
| Subcellular location | Preautophagosomal structure membrane; Peripheral membrane protein; Cytoplasmic side. Note: Enriched at preautophagosomal structure membranes in response to ptdIns3P. Ref.10 |
| Tissue specificity | Ubiquitously expressed (at protein level). Highly expressed in heart, skeletal muscle and pancreas. Expression is down-regulated in pancreatic and in kidney tumors. Ref.1 Ref.10 |
| Sequence similarities | Belongs to the WD repeat SVP1 family. Contains 3 WD repeats. |
