Description: This entry includes the plant root meristem growth factors 1 /2/3 (RGF1/2/3, also known as GOLVEN 11/5/7) from Arabidopsis. They are signaling peptide that maintains the postembryonic root stem cell niche ina PIN2-traffic dependent manner [, , ]. RGF1 (At5g60810) acts as a peptide hormone recognized by receptors such as RGI1 and RGI2 to trigger signaling events including the regulation of RITF1 expression and leading to the production of reactive oxygen species (ROS) in roots to modulate meristem size [].

Protein Domain
Type: Family
Description: Na+/Ca2+exchange proteins are involved in maintaining Ca2+homeostasis ina wide variety of cell types. They are found in both the plasma membraneand intracellular organellar membranes, where they exchange Na+for Ca2+inan electrogenic manner. When located in the plasma membrane, they generallyutilise the transmembrane (TM) Na+concentration gradient in order toextrude Ca2+from cells. Three mammalian isoforms have been cloned to date(NCX1-3), which consist of 920-970 amino acid residues that are predictedto possess 11 or 12 TM domains. Interestingly, they possess a short motif(~30 residues) that is similar to the Na+/K+-ATPase, although its functionis unknown [, ].NCX1 has been found to be predominantly expressed in the heart, where itplays an important role in excitation-contraction coupling, but it is alsoabundant in a variety of other tissues []. NCX2 and NCX3 transcripts havebeen detected in the brain and skeletal muscle [, ]. Homologous Na+/Ca2+exchange proteins have also been found in Caenorhabditis elegans, Drosophila melanogaster andLoligo opalescens (California market squid).

It isalso found in a variety of other tissues, suggesting it serves as ahousekeeping protein, maintaining low cytosolic Ca2+concentration. Alternativelyspliced variants of NCX1 have been identified, expression of which is celltype-specific. Sequence analysis reveals two sets of tandem repeats arefound within the NCX1 protein sequence, which are usually referred to asalpha and beta. The alpha repeats are thought to be involved in the ionbinding and translocation reactions of the exchanger, and the first betarepeat may be part of a regulatory site that responds to Ca2+concentration.

Description: Ribonuclease T2 (RNase T2) is a widespread family of secreted RNases found in every organism examined thus far. This family includes RNase Rh, RNase MC1, RNase LE, and self-incompatibility RNases (S-RNases) [, , , , ]. Plant T2 RNases are expressed during leaf senescence in order to scavenge phosphate from ribonucleotides. They are also expressed in response to wounding or pathogen invasion. S-RNases are thought to prevent self-fertilization by acting as selective cytotoxins of "self"pollen. Generally, RNases have two distinct binding sites: the primary site (B1 site) and the subsite (B2 site), for nucleotides located at the 5'- and 3'- terminal ends of the sissile bond, respectively.The fungal ribonucleases T2 from Aspergillus oryzae, M from Aspergillus saitoi and Rh from Rhizopus niveus are structurally and functionally related 30 Kd glycoproteins []that cleave the 3'-5' internucleotide linkage of RNA via a nucleotide 2',3'-cyclic phosphate intermediate (). Two histidines residues have been shown [, ]to be involved in the catalytic mechanism of RNase T2 and Rh. These residues and the region around them are highly conserved ina number of other RNAses that have been found to be evolutionary related to these fungal enzymes.The structure of ribonuclease T2 is composed of an alpha+beta fold.

Description: Sphingolipids are bioactive compounds found in lower and higher eukaryotes.They are involved in the regulation of various cellular functions, such asgrowth, differentiation and apoptosis, and are believed to be essential ina healthy diet. Sphigolipids are degraded in the lysosome, and theproducts from their hydrolysis are used in other biosynthetic and regulatorypathways in the host.There are a number of lysosomal enzymes involved in the breakdown ofsphinogolipids, and these act in sequence to degrade the moieties []. These enzymes require co-proteins called sphingolipid activator proteins, (SAPs or saposins), to stabilise and activate them as necessary. SAPs are non-enzymatic and usually have a low molecular weight. They are conserved across a wide range of eukaryotes and contain specific saposin domains that aid in the activation of hydrolase enzymes. There have been four human saposins described so far, sharing significant similarity with each otherand with other eukaryotic SAP proteins.Mutations in SAP genes have been linked to a number of conditions. A defectin the saposin B region leads to metachromatic leucodystrophy (MLD), whilea single nucleotide polymorphism in the SAP-C region may give rise toGaucher disease []. More recently, an opportunistic protozoan parasite protein has shown similarity both to the higher and lower eukaryotic saposins. The pore-forming protein isolated from virulent Naegleria fowleri (Brain eating amoeba) has been dubbed Naegleriapore A. It also shares structural similarity with cytolytic bacterial peptides, although this similarity does not extend to the sequence level.This entry represents a group of saposins found specifically in chordates.
