General annotation (Comments)
| Function | Calcium-binding protein that interacts with newly synthesized glycoproteins in the endoplasmic reticulum. It may act in assisting protein assembly and/or in the retention within the ER of unassembled protein subunits. It seems to play a major role in the quality control apparatus of the ER by the retention of incorrectly folded proteins. |
| Subunit structure | Interacts with MAPK3/ERK1 By similarity. Associates with ribosomes By similarity. |
| Subcellular location | Endoplasmic reticulum membrane; Single-pass type I membrane protein. Melanosome. Note: Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Ref.11 Ref.14 |
| Post-translational modification | Phosphorylated at Ser-564 by MAPK3/ERK1. phosphorylation by MAPK3/ERK1 increases its association with ribosomes By similarity. Ref.12 Ref.13 Ref.15 Ref.16 Ref.17 Ref.18 Ref.19 Ref.20 Ref.21 Ref.22 Ref.23 Ref.24 Ref.25 |
| Sequence similarities | Belongs to the calreticulin family. |
