Protein attributes
| Sequence length | 1158 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 | May positively regulate MAP-kinase activity in adipocytes, leading to enhanced adipocyte proliferation and reduced adipocyte differentiation By similarity. May also positively regulate NF-kappa-B activity in macrophages by promoting the phosphorylation and subsequent degradation of I-kappa-B-alpha (NFKBIA), leading to enhanced macrophage inflammatory responsiveness By similarity. Can act as a transcriptional repressor By similarity. |
| Subunit structure | Interacts with GNG5, NFKBIA, MAPK1, MAPK3 and PTEN By similarity. May interact with calmodulin By similarity. Binds to DNA in vitro By similarity. |
| Subcellular location | |
| Tissue specificity | Expressed in osteoblast and visceral fat. Ref.7 |
| Post-translational modification | Phosphorylated by MAPK1 in vitro By similarity. |
| Sequence similarities | Belongs to the peptidase M14 family. Contains 1 F5/8 type C domain. |
| Caution | Although related to peptidase M14 family, lacks the active sites residues and zinc-binding sites, suggesting that it has no carboxypeptidase activity. |
| Sequence caution | The sequence BAD92981.1 differs from that shown. Reason: Erroneous initiation. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q8IUX7-1) 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: Q8IUX7-2) The sequence of this isoform differs from the canonical sequence as follows: 1-457: Missing. 458-495: ITQGRDSSIH...VMYTNGYEEM → MRKWWAPCPG...STALRPASPQ 543-544: AP → ARECGGLAGALSGGGVLGWASRHPAKDNPASLAA | ||||||
