Transcription elongation factor SPT5; May function as a component of the DRB sensitivity-inducing factor complex (DSIF complex), which regulates transcription elongation by RNA polymerase II. DSIF may enhance transcriptional pausing at sites proximal to the promoter, which may in turn facilitate the assembly of an elongation competent RNA polymerase II complex. Belongs to the SPT5 family.

Cyclin-T1.1; Regulatory subunit of the cyclin-dependent kinase pair (CDK9/cyclin T) complex, also called positive transcription elongation factor B (P-TEFb), which is proposed to facilitate the transition from abortive to production elongation by phosphorylating the CTD (carboxy- terminal domain) of the large subunit of RNA polymerase II (RNAP II).

Cyclin-T1.2; Regulatory subunit of the cyclin-dependent kinase pair (CDK9/cyclin T) complex, also called positive transcription elongation factor B (P-TEFb), which is proposed to facilitate the transition from abortive to production elongation by phosphorylating the CTD (carboxy- terminal domain) of the large subunit of RNA polymerase II (RNAP II).

DNA-directed RNA polymerase II subunit RPB1; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Largest and catalytic component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Forms the polymerase active center together with the second largest subunit. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB1 is part of the core element with the central large cl [...]

RNA polymerase II subunit A C-terminal domain phosphatase; During the late stages of oogenesis, dephosphorylates 'Ser-5' of the heptad repeats YSPTSPS in the C-terminal domain of the largest RNA polymerase II subunit ama-1. Similarly, dephosphorylates 'Ser-5' of ama-1 in early embryonic cells prior to the activation of the zygotic transcription program at the 4-cell embryonic stage. May dephosphorylate 'Ser-2' of the ama-1 heptad repeats YSPTSPS in embryonic somatic and germline cells.

Cell division cycle protein 73; Component of the PAF1 complex which is a multifunctional complex involved in transcription initiation via genetic interactions with TATA-binding proteins, elongation and transcription-coupled histone modification; Belongs to the CDC73 family.

DNA damage-binding protein 1; Plays a role in DNA repair. May be a component of an E3 ubiquitin-protein ligase which promotes histone ubiquitination in response to UV irradiation. Histone ubiquitination may be important for subsequent DNA repair (By similarity). Promotes the degradation of the replication licensing factor cdt-1 during S-phase, thereby preventing rereplication of DNA during a single round of cell division.

Polyadenylation and cleavage factor homolog 11.

Transcription elongation factor SPT4; May function as a component of the DRB sensitivity-inducing factor complex (DSIF complex), which regulates transcription elongation by RNA polymerase II. DSIF may enhance transcriptional pausing at sites proximal to the promoter, which may in turn facilitate the assembly of an elongation competent RNA polymerase II complex.
