Protein attributes
| Sequence length | 3169 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Extracellular matrix protein required for maintenance of the integrity of the skin epithelium and for maintenance of renal epithelia. May be required for epidermal adhesion. Ref.5 |
| Subcellular location | Cell membrane; Single-pass type I membrane protein; Extracellular side Potential. |
| Domain | The Calx-beta domains bind calcium with high affinity and undergo a major conformational shift upon binding By similarity. |
| Involvement in disease | Fraser syndrome (FRASS) [MIM:219000]: Multisystem malformation usually comprising cryptophthalmos, cutaneous syndactyly, ear abnormalities, renal agenesis and congenital heart defects. |
| Sequence similarities | Belongs to the FRAS1 family. Contains 5 Calx-beta domains. Contains 12 CSPG (NG2) repeats. |
| Sequence caution | The sequence BAC87040.1 differs from that shown. Reason: Erroneous initiation. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q5SZK8-1) 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: Q5SZK8-2) The sequence of this isoform differs from the canonical sequence as follows: 2663-2667: LNLVQ → QIYNI 2668-3169: Missing. | ||||||
| Note: No experimental confirmation available. |
