IPR030300 is a Signal recognition particle 43kDa protein, chromodomain 3.
<p>This group of proteins includes chloroplast signal-recognition particle 43kDa protein (CpSRP43) and similar plant proteins. In Arabidopsis, CpSRP43 (AT2G47450, CAO) is a component of the chloroplast signal recognition particle pathway that is involved in LHCP (light-harvesting chlorophyll a/b-binding protein) targeting. LHCPs are synthesised in the cytoplasm, and after import into the chloroplast, they are targeted and inserted into the thylakoid membrane. In addition, CpSRP43 functions as a chaperone preventing aggregation of LHCP following import into the chloroplast [[cite:PUB00072211], [cite:PUB00072212]].</p> <p>This entry represents the chromodomain 3 of SRP43, which appear to play a role in the functional organization of the eukaryotic nucleus. This domain is involved in the binding activity of these proteins to methylated histone tails and maybe RNA [[cite:PUB00101743]].</p>

GO predictions are based solely on the InterPro-to-GO mappings published by EMBL-EBI, which are in turn based on the mapping of predicted domains to the InterPro dataset. The InterPro-to-GO mapping was last updated on , while the GO metadata was last updated on .
| GO term | Namespace | Name | Definition | Relationships |
|---|---|---|---|---|
| Biological process | Response to light stimulus | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light. | ||
| Cellular component | Chloroplast | A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma. | ||
| Biological process | Protein import into chloroplast thylakoid membrane | The import of proteins into the chloroplast thylakoid membranes. Proteins that are destined for the thylakoid lumen require two uptake-targeting sequences: the first targets the protein to the stroma, and the second targets the protein from the stroma to the thylakoid lumen. Four separate thylakoid-import systems deal with the proteins once they are in the stroma. | ||
| Cellular component | Signal recognition particle, chloroplast targeting | A complex consisting of a protein and RNA component which binds the signal sequence of some proteins and facilitates their export to the chloroplast. |
