c_xf7wylzhrqlz | The hairpin precursors (represented here) are predicted based on base pairing and cross-species conservation; their extents are not known. In this case, the mature sequence is excised from the 5' arm of the hairpin. miR-219 has also been linked with NMDA receptor signalling in humans by targeting CaMKIIγ (a kind of pro... | Mir-219 microRNA precursor family |
c_uqf388uv4382 | In molecular biology, the myogenic determination factor 5 proteins are a family of proteins found in eukaryotes. This family includes the Myf5 protein, which is responsible for directing cells to the skeletal myocyte lineage during development. Myf5 is likely to act in a similar way to the other MRF4 proteins such as M... | Myogenic determination factor 5 |
c_kucs5sndq0qi | Myogenic determination factor 5 proteins contain three conserved protein domains. A C-terminal Myf5 domain, a central basic helix-loop-helix (bHLH) domain and an N-terminal basic domain. The bHLH region mediates specific DNA binding. | Myogenic determination factor 5 |
c_sxfd9mi2mhql | With 12 residues of the basic domain involved in DNA binding. The basic domain forms an extended alpha helix in the structure. == References == | Myogenic determination factor 5 |
c_1k2ybpkleykf | In molecular biology, the octopine dehydrogenase family of enzymes act on the CH-NH substrate bond using NAD(+) or NADP(+) as an acceptor. The family includes octopine dehydrogenase EC 1.5.1.11, nopaline dehydrogenase EC 1.5.1.19, lysopine dehydrogenase EC 1.5.1.16 and opine dehydrogenase EC 1.5.1.-. NADPH is the prefe... | Octopine dehydrogenase family |
c_r8tjaft0w9cg | In bacteria, some of these opine dehydrogenases are involved in crown gall tumours that are produced by Agrobacterium spp., and which encode for the opine dehydrogenases on a Ti-plasmid. These bacteria can transfer a portion of this plasmid (T-DNA) to a susceptible plant cell; the T-DNA then integrates into the plant n... | Octopine dehydrogenase family |
c_yuv72ee2lb4c | Opine dehydrogenases are also found in the marine invertebrate cephalopods (octopuses, squid, and cuttlefish). For example, in marine cephalopods, octopine dehydrogenase activity in mantle muscle is significantly correlated with a species' ability to buffer the acidic end products of anaerobic metabolism, with activity... | Octopine dehydrogenase family |
c_ve0gwk7h0ijg | In molecular biology, the plant calmodulin-binding domain is a protein domain found repeated in a number of plant calmodulin-binding proteins. These domains are thought to constitute the calmodulin-binding domains of these proteins. Binding of the proteins to calmodulin depends on the presence of calcium ions. These pr... | Plant calmodulin-binding domain |
c_bko0zpjbg1zl | In molecular biology, the polyketide synthesis cyclase family of proteins includes a number of cyclases involved in polyketide synthesis in a number of actinobacterial species. Aromatic polyketides are assembled by a type II (iterative) polyketide synthase in bacteria. Iterative type II polyketide syntheses produce pol... | Polyketide synthesis cyclase family |
