Domain Architecture (Details)
InterPro domains unassigned to SynO:
This group of proteins is found in sodium.otassium.nd calcium ion channels proteins. The proteins have 6 transmembrane helices in which the last two helices flank a loop which determines ion selectivity. In some Na channels proteins the domain is repeated four times.hereas in others (e.g. K channels) the protein forms a tetramer in the membrane. A bacterial structure of the protein is known for the last two helices but is not included in the Pfam family due to it lacking the first four helices.

MutT is a small bacterial protein (~12-15Kd) involved in the GO system responsible for removing an oxidatively damaged form of guanine (8-hydroxy- guanine or 7.-dihydro-8-oxoguanine) from DNA and the nucleotide pool. 8-oxo-dGTP is inserted opposite dA and dC residues of template DNA with near equal efficiency.eading to A.T to G.C transversions. MutT specifically degrades 8-oxo-dGTP to the monophosphate.ith the concomitant release of pyrophosphate. A short conserved N-terminal region of mutT (designated the MutT domain) is also found in a variety of other prokaryotic.iral and eukaryotic proteins . The generic name NUDIX hydrolases (NUcleoside DIphosphate linked to some other moiety X) has been coined for this domain family . The family can be divided into a number of subgroups.f which MutT anti- mutagenic activity represents only one type; most of the rest hydrolyse diverse nucleoside diphosphate derivatives (including ADP-ribose.DP- mannose.DP-glucose.ADH.DP-sugars.NTP and NTP).
  IPR000086:NUDIX hydrolase
Transient receptor potential (Trp) and related proteins are thought to beCa2+ ion channel subunits that mediate capacitative Ca2+ entry in responseto a range of external and internal cell stimuli. Such Ca2+ entry is thoughtto be an essential component of cellular responses to many hormones andgrowth factors.nd acts to replenish intracellular Ca2+ stores that havebeen emptied through the action of inositol triphosphate (IP3) and otheragents. In non-excitable cells..e. those that lack voltage-gated Ca2+channels.uch as hepatocytes.his mode of Ca2+ entry is thought to be animportant step in generating the oscillations of intracellular Ca2+concentration that characterise their response to stimulatory agents .Studies on the visual transduction system in Drosophila led to the molecularcloning of Trp and the cDNA of a related protein.rp-like.hich showsimilarity to voltage gated Ca2+ channels in the regions known as S3 throughS6.ncluding the S5-S6 linker that forms the ion-selective channel pore .This provided evidence that Trp and/or related proteins might form mammaliancapacitative Ca2+ entry channels. They have varying lengths (usually 800-1000amino acid residues).nd hydropathy analyses suggest that they have six ormore transmebrane (TM) regions.lanked by cytosolic N- and C-termini.
