Primary Identifier | IPR041679 | Type | Domain |
Short Name | DNA2/NAM7-like_C |
description | This domain contains a P-loop motif that is characteristic of the AAA superfamily. Proteins containing this domain are DEAD-like helicases belonging to superfamily (SF)1, a diverse family of proteins involved in ATP-dependent RNA or DNA unwinding. Similar to SF2 helicases, SF1 helicases do not form toroidal structures like SF3-6 helicases. Their helicase core consists of two similar protein domains that resemble the fold of the recombination protein RecA [, , ].Proteins containing this domain include helicases, such as Dna2 an Nam7. Dna2 is a DNA replication factor with single-stranded DNA-dependent ATPase, ATP-dependent nuclease, (5'-flap endonuclease) and helicase activities [, ]. Nam7 (also known as Upf1) is an ATP-dependent RNA helicase involved in the nonsense-mediated mRNA decay (NMD) pathway []. This domain can also be found in some virus polyproteins. This domain is also known as HelicC. |
