| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Regulates Tat transactivation activity through direct interaction. May be a cellular factor for HIV-1 gene expression and viral replication. Ref.2 |
| Subunit structure | Component of the 7SK snRNP complex at least composed of P-TEFb (composed of CDK9 and CCNT1/cyclin-T1), HEXIM1, HEXIM2, BCDIN3, SART3 proteins and 7SK and U6 snRNAs. Interacts with HIV-1 Tat. Interacts with EIF2C1 and EIF2C2. Ref.2 Ref.7 Ref.9 |
| Subcellular location | Cytoplasm. Nucleus speckle. Note: Localized in speckles. Expressed in the nucleus of all of the malignant tumor cell lines tested and the majority of cancer tissues with various histologies, including squamous cell carcinomas (SCC), adenocarcinomas, melanomas and leukemias cells. However, this protein is undetectable in the nucleus of any cell lines of nonmalignant cells or normal tissues, except for the testis. Expressed in the cytoplasm of all the proliferating cells, including normal and malignant cells, but not in normal tissues, except for the testis and the fetal liver. Ref.1 Ref.2 |
| Tissue specificity | Ubiquitously expressed. Ref.2 |
| Involvement in disease | Disseminated superficial actinic porokeratosis 1 (DSAP1) [MIM:175900]: Autosomal dominant disorder, characterized by multiple superficial keratotic lesions surrounded by a slightly raised keratotic border, developing during the third or fourth decade of life on sun-exposed areas of skin. |
| Sequence similarities | Contains 8 HAT repeats. Contains 2 RRM (RNA recognition motif) domains. |

Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q15020-1) 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: Q15020-2) The sequence of this isoform differs from the canonical sequence as follows: 351-364: SQYLDRQLKVKDLV → RSTTESKGFGFICT 365-963: Missing. | ||||||
| Note: May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 3 (identifier: Q15020-3) The sequence of this isoform differs from the canonical sequence as follows: 105-129: LSINVYDYNCHVDLIRLLRLEGELT → VGPGVGSGHLPVFQVLGSPCPGPPP 130-963: Missing. | ||||||
| Note: No experimental confirmation available. |
