Protein attributes
| Sequence length | 1835 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Involved in transcriptional activation and repression of select genes by chromatin remodeling (alteration of DNA-nucleosome topology). Required for the stability of the SWI/SNF chromatin remodeling complex SWI/SNF-B (PBAF). May be involved in targeting the complex to different genes. May be involved in regulating transcriptional activation of cardiac genes. |
| Subunit structure | Component of the SWI/SNF-B (PBAF) chromatin remodeling complex, at least composed of SMARCA4/BRG1, SMARCB1/BAF47, ACTL6A/BAF53A or ACTL6B/BAF53B, SMARCE1/BAF57, SMARCD1/BAF60A, SMARCD2/BAF60B, perhaps SMARCD3/BAF60C, SMARCC1/BAF155, SMARCC2/BAF170, PB1/BAF180, ARID2/BAF200, ARID1A/BAF250A or ARID1B/BAF250B and actin. Interacts with SRF. Forms complexes with SRF and SRF cofactors MYOCD, NKX2-5 and SRFBP1. |
| Subcellular location | |
| Tissue specificity | Highly expressed in heart and testis. |
| Developmental stage | Up-regulated in adult heart (at protein level). |
| Sequence similarities | Contains 1 ARID domain. Contains 1 C2H2-type zinc finger. |
| Sequence caution | The sequence AAU20329.2 differs from that shown. Reason: Miscellaneous discrepancy. Differs from position 1094 onward for unknown reason. |
