TBA2_ARATH - PTM Information in dbPTM

Basic Information of Protein

Overview of Protein Modification Sites with Functional and Structural Information
UniProt ID	TBA2_ARATH
UniProt AC	B9DGT7
Protein Name	Tubulin alpha-2 chain
Gene Name	TUBA2
Organism	Arabidopsis thaliana (Mouse-ear cress).
Sequence Length	450
Subcellular Localization	Cytoplasm, cytoskeleton.
Protein Description	Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain..
