DSP4_ARATH - PTM Information in dbPTM

Basic Information of Protein

Overview of Protein Modification Sites with Functional and Structural Information
UniProt ID	DSP4_ARATH
UniProt AC	Q9FEB5
Protein Name	Phosphoglucan phosphatase DSP4, chloroplastic
Gene Name	DSP4
Organism	Arabidopsis thaliana (Mouse-ear cress).
Sequence Length	379
Subcellular Localization	Plastid, chloroplast . Associated with starch granule.
Protein Description	Starch granule-associated phosphoglucan phosphatase involved in the control of starch accumulation. Acts as major regulator of the initial steps of starch degradation at the granule surface. Functions during the day by dephosphorylating the night-accumulated phospho-oligosaccharides. Can release phosphate from both the C6 and the C3 positions, but dephosphorylates preferentially the C6 position. [PubMed: 20018599]
