General annotation (Comments)
| Function | Metalloproteinase which specifically cleaves IGFBP-5. Shows limited proteolysis toward IGFBP-3. Ref.1 |
| Catalytic activity | Cleavage of the 143-Ser-|-Lys-144 bond in insulin-like growth factor binding protein (IGFBP)-5. |
| Cofactor | Binds 1 zinc ion per subunit By similarity. |
| Subunit structure | Monomer. |
| Subcellular location | Secreted By similarity. |
| Tissue specificity | Expressed abundantly in placenta, and non-pregnant mammary gland with low expression in the kidney, fetal brain and pancreas. Ref.1 Ref.2 |
| Sequence similarities | Belongs to the peptidase M43B family. Contains 5 Sushi (CCP/SCR) domains. |
| Sequence caution | The sequence AAL17779.1 differs from that shown. Reason: Erroneous initiation. The sequence AAL17780.1 differs from that shown. Reason: Erroneous initiation. The sequence CAC11134.1 differs from that shown. Reason: Erroneous initiation. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q9BXP8-1) Also known as: Papp-e(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: Q9BXP8-2) Also known as: Papp-e(2); The sequence of this isoform differs from the canonical sequence as follows: 811-827: DDNCTDNFTPNQVARMH → GITTVLFCFLLRIHGGL 828-1791: Missing. |
