Protein attributes
| Sequence length | 428 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | May act as a scaffolding protein within caveolar membranes, functionally participating in formation of caveolae or caveolae-like vesicles. May be involved in epidermal cell adhesion and epidermal structure and function. |
| Subunit structure | Heterooligomeric complex of flotillin-1 and flotillin-2 and caveolin-1 and caveolin-2 By similarity. Interacts with ECM29. Ref.7 |
| Subcellular location | Cell membrane; Peripheral membrane protein. Membrane › caveola; Peripheral membrane protein. Endosome. Note: Membrane-associated protein of caveolae. Ref.7 |
| Tissue specificity | In skin, expressed in epidermis and epidermal appendages but not in dermis. Expressed in all layers of the epidermis except the basal layer. In hair follicles, expressed in the suprabasal layer but not the basal layer. Also expressed in melanoma and carcinoma cell lines, fibroblasts and foreskin melanocytes. |
| Sequence similarities | Belongs to the band 7/mec-2 family. Flotillin subfamily. |
| Sequence caution | The sequence AAA65729.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. |
