PAP1_ARATH - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: PAP1_ARATH
• UniProt AC: O81439
• Protein Name: Probable plastid-lipid-associated protein 1, chloroplastic
• Gene Name: PAP1
• Organism: Arabidopsis thaliana (Mouse-ear cress).
• Sequence Length: 318
• Subcellular Localization: Plastid, chloroplast, plastoglobule . Plastid, chloroplast thylakoid. Located in the elaioplast, a tapetum-specific plastidial lipid organelle.
• Protein Description: Probably involved in light/cold stress-related jasmonate (JA) biosynthesis. Contributes to the protection of photosystem II (PSII) against light stress..
