TBB2B_RAT - PTM Information in dbPTM

Basic Information of Protein

• UniProt ID: TBB2B_RAT
• UniProt AC: Q3KRE8
• Protein Name: Tubulin beta-2B chain
• Gene Name: Tubb2b
• Organism: Rattus norvegicus (Rat).
• Sequence Length: 445
• Subcellular Localization: Cytoplasm, cytoskeleton .
• Protein Description: Tubulin is the major constituent of microtubules. [PubMed: 19465910 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. Plays a critical role in proper axon guidance in both central and peripheral axon tracts. Implicated in neuronal migration (By similarity]
