| Protein existence | Evidence at protein level |
General annotation (Comments)
| Subunit structure | Interacts with heparin. Ref.1 |
| Subcellular location | Secreted Probable. Cell membrane; Peripheral membrane protein; Extracellular side Ref.1. |
| Tissue specificity | Highly expressed in the kidney, brain and testis and to a lower extent in heart, liver and small intestine. Ref.1 |
| Induction | Up-regulated by IL1B/interleukin-1 beta and IL6/interleukin-6. Ref.1 |
| Post-translational modification | Proteolytically cleaved into 2 chains of about 70 and 130 kDa. The fragments are not connected by disulfide bonds. Ref.1 |
| Sequence similarities | Belongs to the protease inhibitor I39 (alpha-2-macroglobulin) family. [View classification] Contains 1 Kazal-like domain. |
| Sequence caution | The sequence BAC11400.1 differs from that shown. Reason: Erroneous initiation. |

Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q8IZJ3-1) 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: Q8IZJ3-2) The sequence of this isoform differs from the canonical sequence as follows: 1809-1815: RVTAGPR → SQSGFSS 1816-1885: Missing. | ||||||
| Note: No experimental confirmation available. |
