| Protein names | Recommended name: Myb-binding protein 1A | ||||
| Gene names |
| ||||
| Organism | Homo sapiens (Human) [Reference proteome] | ||||
| Taxonomic identifier | 9606 [NCBI] | ||||
| Taxonomic lineage | Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo![]() |
Protein attributes
| Sequence length | 1328 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | May activate or repress transcription via interactions with sequence specific DNA-binding proteins. Repression may be mediated at least in part by histone deacetylase activity (HDAC activity) By similarity. |
| Subunit structure | Binds to and represses JUN and MYB via the leucine zipper regions present in these proteins. Also binds to and represses PPARGC1A: this interaction is abrogated when PPARGC1A is phosphorylated by MAPK1/ERK. Binds to and stimulates transcription by AHR. Binds to KPNA2. Component of the B-WICH complex, at least composed of SMARCA5/SNF2H, BAZ1B/WSTF, SF3B1, DEK, MYO1C, ERCC6, MYBBP1A and DDX21 By similarity. Ref.7 |
| Subcellular location | Cytoplasm. Nucleus. Nucleus › nucleolus. Note: Shuttles between the nucleus and cytoplasm. Nuclear import may be mediated by KPNA2, while export appears to depend partially on XPO1/CRM1 By similarity. Predominantly nucleolar. Ref.5 |
| Sequence caution | The sequence CAB66530.1 differs from that shown. Reason: Erroneous initiation. |
Ontologies
Alternative products
| This entry describes 2 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q9BQG0-1) 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: Q9BQG0-2) The sequence of this isoform differs from the canonical sequence as follows: 1322-1328: VRKAGKP → TLRFTISSSKK | ||||||
| Note: May be due to competing donor and acceptor splice sites. |
