Required in the control of cell shape.
3 Q8WWQ0 PH-interacting protein 1821Probable regulator of the insulin and insulin-like growth factor signaling pathways.

4 Q9NSI6 Bromodomain and WD repeat-containing protein 1 2320May be a transcriptional activator.
May be involved in chromatin remodeling (By similarity).
Plays a role in the regulation of cell morphology and cytoskeletal organization.
Required in the control of cell shape.
5 Q8IZX4 Transcription initiation factor TFIID subunit 1-like 1826"May act as a functional substitute for TAF1/TAFII250 during male meiosis, when sex chromosomes are transcriptionally silenced".
6 Q58F21 Bromodomain testis-specific protein 947"Testis-specific chromatin protein that specifically binds histone H4 acetylated at 'Lys-5' and 'Lys-8' (H4K5ac and H4K8ac, respectively) and plays a key role in spermatogenesis (PubMed:22464331, PubMed:22901802).
Required in late pachytene spermatocytes: plays a role in meiotic and post-meiotic cells by binding to acetylated histones at the promoter of specific meiotic and post-meiotic genes, facilitating their activation at the appropriate time (PubMed:22901802).
In the post-meiotic phase of spermatogenesis, binds to hyperacetylated histones and participates in their general removal from DNA (PubMed:22901802).
Also recognizes and binds a subset of butyrylated histones: able to bind histone H4 butyrylated at 'Lys-8' (H4K8ac), while it is not able to bind H4 butyrylated at 'Lys-5' (H4K5ac) (By similarity).
Also acts as a component of the splicing machinery in pachytene spermatocytes and round spermatids and participates in 3'-UTR truncation of specific mRNAs in post-meiotic spermatids (By similarity).
Required for chromocenter organization, a structure comprised of peri-centromeric heterochromatin".
7 Q15059 Bromodomain-containing protein 3 726"Chromatin reader that recognizes and binds hyperacetylated chromatin and plays a role in the regulation of transcription, probably by chromatin remodeling and interaction with transcription factors (PubMed:18406326, PubMed:27105114).
Regulates transcription by promoting the binding of the transcription factor GATA1 to its targets (By similarity)".
8 Q86U86 Protein polybromo-1 1689Involved 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).
Acts as a negative regulator of cell proliferation.
9 Q9H0E9 Bromodomain-containing protein 8 1235"May act as a coactivator during transcriptional activation by hormone-activated nuclear receptors (NR).
Isoform 2 stimulates transcriptional activation by AR/DHTR, ESR1/NR3A1, RXRA/NR2B1 and THRB/ERBA2.
At least isoform 1 and isoform 2 are components of the NuA4 histone acetyltransferase (HAT) complex which is involved in transcriptional activation of select genes principally by acetylation of nucleosomal histones H4 and H2A.
This modification may both alter nucleosome - DNA interactions and promote interaction of the modified histones with other proteins which positively regulate transcription.
This complex may be required for the activation of transcriptional programs associated with oncogene and proto-oncogene mediated growth induction, tumor suppressor mediated growth arrest and replicative senescence, apoptosis, and DNA repair.
NuA4 may also play a direct role in DNA repair when recruited to sites of DNA damage.
Component of a SWR1-like complex that specifically mediates the removal of histone H2A.
Z/H2AFZ from the nucleosome".
10 O60885 Bromodomain-containing protein 4 1362"Chromatin reader protein that recognizes and binds acetylated histones and plays a key role in transmission of epigenetic memory across cell divisions and transcription regulation.
Remains associated with acetylated chromatin throughout the entire cell cycle and provides epigenetic memory for postmitotic G1 gene transcription by preserving acetylated chromatin status and maintaining high-order chromatin structure.
During interphase, plays a key role in regulating the transcription of signal-inducible genes by associating with the P-TEFb complex and recruiting it to promoters: BRD4 is required to form the transcriptionally active P-TEFb complex by displacing negative regulators such as HEXIM1 and 7SKsnRNA complex from P-TEFb, thereby transforming it into an active form that can then phosphorylate the C-terminal domain (CTD) of RNA polymerase II.
Promotes phosphorylation of 'Ser-2' of the C-terminal domain (CTD) of RNA polymerase II.
According to a report, directly acts as an atypical protein kinase and mediates phosphorylation of 'Ser-2' of the C-terminal domain (CTD) of RNA polymerase II; these data however need additional evidences in vivo (PubMed:22509028).
In addition to acetylated histones, also recognizes and binds acetylated RELA, leading to further recruitment of the P-TEFb complex and subsequent activation of NF-kappa-B.
Also acts as a regulator of p53/TP53-mediated transcription: following phosphorylation by CK2, recruited to p53/TP53 specific target promoters.
; Isoform B: Acts as a chromatin insulator in the DNA damage response pathway.
Inhibits DNA damage response signaling by recruiting the condensin-2 complex to acetylated histones, leading to chromatin structure remodeling, insulating the region from DNA damage response by limiting spreading of histone H2AFX/H2A.

11 P25440 Bromodomain-containing protein 2 801"May play a role in spermatogenesis or folliculogenesis (By similarity).
Binds hyperacetylated chromatin and plays a role in the regulation of transcription, probably by chromatin remodeling.
Regulates transcription of the CCND1 gene.
Plays a role in nucleosome assembly".
