General annotation (Comments)
| Function | Isoform PMR1: Endonuclease selectively degrading some target mRNAs while they are engaged by translating ribosomes, among which albumin and beta-globin mRNAs. Ref.6 Ref.7 |
| Catalytic activity | 2 phenolic donor + H2O2 = 2 phenoxyl radical of the donor + 2 H2O. |
| Cofactor | Binds 1 calcium ion per subunit By similarity. Binds 1 heme B (iron-protoporphyrin IX) group covalently per subunit By similarity. |
| Subcellular location | Isoform PMR1: Cytoplasm. Note: Associates with polysomes. Ref.6 |
| Tissue specificity | the 57 kDa isoform PMR1 is the only form detected at protein levels in human cell lines. Ref.7 |
| Post-translational modification | Phosphorylation by SRC on tyrosine residues is required for targeting to polysomes. |
| Sequence similarities | Belongs to the peroxidase family. XPO subfamily. Contains 4 Ig-like C2-type (immunoglobulin-like) domains. Contains 5 LRR (leucine-rich) repeats. Contains 1 LRRCT domain. Contains 1 LRRNT domain. Contains 1 VWFC domain. |
| Sequence caution | The sequence AAX70929.1 differs from that shown. Reason: Frameshift at positions 127 and 132. The sequence BAB71713.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAD18663.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence EAW86707.1 differs from that shown. Reason: Erroneous gene model prediction. |
