Cyclin-dependent kinase 7; Serine/threonine kinase involved in cell cycle control and in RNA polymerase II-mediated RNA transcription. Required for maintaining chromosome ploidy. May phosphorylate the large subunit of RNA polymerase II, ama-1; Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. CDC2/CDKX subfamily.

Probable cyclin-dependent kinase 9; Essential member 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 (C- terminal domain) of the large subunit of RNA polymerase II (RNAP II) and spt-5.

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 [...]

Cyclin-dependent kinase 12; Cyclin-dependent kinase which displays CTD kinase activity: hyperphosphorylates 'Ser-2' in the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit, thereby acting as a key regulator of transcription elongation. Required for normal reproduction.

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.

BH4_AAA_HYDROXYL_2 domain-containing protein.

G_PROTEIN_RECEP_F1_2 domain-containing protein; Belongs to the G-protein coupled receptor 1 family.

Guanine nucleotide-binding protein subunit beta-1; Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction. In the early embryo, controls the magnitude of the forces acting on centrosomes but is not required for generating asymmetric forces.

Guanine nucleotide-binding protein subunit beta-2; Guanine nucleotide-binding proteins (G proteins) are involved as a modulator or transducer in various transmembrane signaling systems. The beta and gamma chains are required for the GTPase activity, for replacement of GDP by GTP, and for G protein-effector interaction.
