The breakdown into simpler components of organic acids, any acidic compound containing carbon in covalent linkage.

nuclear origin of replication recognition complex

A multisubunit complex that is located at the replication origins of a chromosome in the nucleus.

The series of molecular signals initiated by binding of Wnt protein to a receptor on the surface of the target cell.

DNA-directed RNA polymerase II, core complex

RNA polymerase II, one of three eukaryotic nuclear RNA polymerases, is a multisubunit complex; it produces mRNAs, snoRNAs, and some of the snRNAs. Two large subunits comprise the most conserved portion including the catalytic site and share similarity with other eukaryotic and bacterial multisubunit RNA polymerases. The largest subunit of RNA polymerase II contains an essential carboxyl-terminal domain (CTD) composed of a variable number of heptapeptide repeats (YSPTSPS). The remainder of the complex is composed of smaller subunits (generally ten or more), some of which are also found in RNA polymerases I and III. Although the core is competent to mediate ribonucleic acid synthesis, it requires additional factors to select the appropriate template.

Catalysis of the reaction: ATP + beta-adrenergic receptor = ADP + phospho-beta-adrenergic receptor.

RNA polymerase III, one of three eukaryotic nuclear RNA polymerases, is a multisubunit complex; it produces tRNAs and some of the snRNAs. Two large subunits comprise the most conserved portion including the catalytic site and share similarity with other eukaryotic and bacterial multisubunit RNA polymerases. The remainder of the complex is composed of smaller subunits (generally ten or more), some of which are also found in RNA polymerase I and others which are found in all three nuclear RNA polymerases. Although the core is competent to mediate ribonucleic acid synthesis, it requires additional factors to select the appropriate template.

Any complex, distinct from RNA polymerase, including one or more polypeptides capable of binding DNA at promoters or at cis-acting regulatory sequences, and regulating transcription.
