STEP1_ARATH - PTM Information in dbPTM

Basic Information of Protein

Overview of Protein Modification Sites with Functional and Structural Information
UniProt ID	STEP1_ARATH
UniProt AC	Q9M7I9
Protein Name	Stress enhanced protein 1, chloroplastic {ECO:0000305}
Gene Name	SEP1 {ECO:0000303\|PubMed:10725357}
Organism	Arabidopsis thaliana (Mouse-ear cress).
Sequence Length	146
Subcellular Localization	Plastid, chloroplast thylakoid membrane Multi-pass membrane protein .
Protein Description	May be involved in non-photochemical quenching, a process that maintains the balance between dissipation and utilization of light energy to minimize generation of oxidizing molecules, thereby protecting the plant against photo-oxidative damage (By similarity). May play a photoprotective role in the thylakoid membrane in response to light stress (Probable)..
