Protein attributes
| Sequence length | 906 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 | Probable ligand for integrin in the brain. This is a non catalytic metalloprotease-like protein. Involved in regulation of cell adhesion and spreading and in inhibition of cell proliferation. Neuronal receptor for LGI1. Ref.5 Ref.7 Ref.8 |
| Subunit structure | Interacts with LGI1 and can bind to LGI4 By similarity. Interacts through its C-terminal region with YWHAB/14-3-3 beta and YWHAZ/14-3-3 zeta but not with YWHAE/14-3-3 epsilon or YWHAH/14-3-3 eta. |
| Subcellular location | |
| Tissue specificity | Highly expressed in the brain and in some high-grade but not low-grade gliomas. Detected slightly or not at all in other tissues. Ref.8 |
| Post-translational modification | The precursor is cleaved by a furin endopeptidase By similarity. |
| Sequence similarities | Contains 1 disintegrin domain. Contains 1 EGF-like domain. Contains 1 peptidase M12B domain. |

Alternative products
| This entry describes 5 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q9P0K1-1) Also known as: Epsilon; 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: Q9P0K1-2) Also known as: Delta; The sequence of this isoform differs from the canonical sequence as follows: 768-803: Missing. 859-859: E → EYLNPWFKRDYNVAKWVEDVNKNTEEPYFR | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 3 (identifier: Q9P0K1-3) Also known as: Alpha; The sequence of this isoform differs from the canonical sequence as follows: 860-906: Missing. | ||||||
| Isoform 4 (identifier: Q9P0K1-4) Also known as: Beta; The sequence of this isoform differs from the canonical sequence as follows: 768-803: Missing. 860-906: Missing. | ||||||
| Isoform 5 (identifier: Q9P0K1-5) The sequence of this isoform differs from the canonical sequence as follows: 768-803: Missing. |
