Protein attributes
| Sequence length | 421 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Specifically acetylates 'Lys-40' in alpha-tubulin on the lumenal side of microtubules. May affect microtubule stability and regulate microtubule dynamics. May be involved in neuron development. Ref.7 |
| Catalytic activity | Acetyl-CoA + [alpha-tubulin]-L-lysine = CoA + [alpha-tubulin]-N(6)-acetyl-L-lysine. Ref.7 |
| Sequence similarities | Belongs to the acetyltransferase ATAT1 family. |

| This entry describes 7 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q5SQI0-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q5SQI0-2) The sequence of this isoform differs from the canonical sequence as follows: 1-12: Missing. 13-36: ERITVLDQHLRPPARRPGTTTPAR → MWLTWPFCFLTITLREEGVCHLES | ||||||
| Isoform 3 (identifier: Q5SQI0-3) The sequence of this isoform differs from the canonical sequence as follows: 195-218: RPPAPSLRATRHSRAAAVDPTPAA → P | ||||||
| Isoform 4 (identifier: Q5SQI0-4) The sequence of this isoform differs from the canonical sequence as follows: 323-333: RGTPPGLVAQS → SSLPRSEESRY 334-421: Missing. | ||||||
| Isoform 5 (identifier: Q5SQI0-5) The sequence of this isoform differs from the canonical sequence as follows: 324-421: Missing. | ||||||
| Isoform 6 (identifier: Q5SQI0-6) The sequence of this isoform differs from the canonical sequence as follows: 195-218: RPPAPSLRATRHSRAAAVDPTPAA → P 323-333: RGTPPGLVAQS → SSLPRSEESRY 334-421: Missing. | ||||||
| Isoform 7 (identifier: Q5SQI0-7) The sequence of this isoform differs from the canonical sequence as follows: 195-218: RPPAPSLRATRHSRAAAVDPTPAA → P 324-421: Missing. |
