==Annotated Information==ClpB-cytoplasmic (ClpB-cyt)/Hsp100 is an important chaperone protein in rice. Cellular expression of OsClpB-cyt transcript is governed by heat stress, metal stress, and developmental cues.

Function

Please input function information here. ClpB-cyt/HSP100 protein acts as chaperone, mediating disaggregation of denatured proteins. Previous studies have shown that ClpB-cyt/HSP100 gene belongs to the group class I Clp ATPase proteins and ClpB-cyt/HSP100 transcript is regulated by heat stress and developmental cues[1].

Expression

Please input expression information here. HSP100 is a major heat-regulated protein family in diverse organisms. Across the living systems, common features of HSP100 chaperone action include transient interactions with non-native protein species, in the prevention of aggregation and promotion of correct folding and assembly, or in unfolding for translocation or targeting to proteases. Singla and Grover showed that homologues of yeast HSP104 protein are expressed in heat shocked rice seedlings. It was subsequently established that apart from heat, rice HSP100 expression is developmentally- controlled as seeds and developing embryos of rice show high constitutive levels of this protein.

Hsp100 transcript/protein expression is induced during heat stress in Arabidopsis, soybean, rice, maize, tobacco and wheat. There are also indications that Hsp100 transcript/ protein is induced by desiccation (Shen et al 2003), low temperature and ABA. Apart from stress-regulation, Hsp100 transcript and protein are developmentally regulated in plants. In non-stressed maize, Hsp100 is expressed to a high level in the tassel at the pre-meiosis stage, the ear (including silks) and the developing endosperm and embryo.

Evolution

You can also add sub-section(s) at will. HSP100 proteins belong to ClpB family. Clp ATPases maintain quality of cellular proteins by performing the function of molecular chaperones and energy dependent proteases. Clp (Caseinolytic Protease) system was first identified as a heat shock inducible, multicomponent, ATP-dependent protease complex able to hydrolyze casein. Subsequent studies showed that the Clp system can hydrolyze numerous other proteins and peptides in both aggregated and non-aggregated forms Clp ATPases fall within the AAA+ superfamily of ATPases associated with a substantially broader range of biological processes. Class I ATPases (ClpA, ClpB, ClpC, ClpD) have two ATP binding domains and class II Clp ATPases (ClpM, ClpN, ClpX, ClpY) have one ATP binding domain. Clp proteins are localized in various cellular organelles in plants. Basically, Clp system members include three non-homologous gene families: ClpABCXY, ClpP and ClpQ. ClpACX members (but not ClpB) facilitate the activity of ClpP and some, such as ClpA and ClpX,can function as independent chaperones in roles analogous to those of DnaK and DnaJ proteins. In contrast, ClpP proteolytic subunit exhibits low levels of peptidolytic activity. Further, when ClpP is complexed with ClpA, ClpC or ClpX, active holoenzymes which are able to cleave denatured proteins are formed. ClpAP, ClpXP and HslUV proteases are similar in design to the eukaryotic 26 S proteasome, with the ATPase subunits guarding the entrance to the proteolytic chamber. Clp proteases in bacterial and eukaryotic systems have been implicated in vital cellular processes such as sporulation, DNA replication, protein turnover, stress tolerance and acclimation and regulation of gene expression. ClpB is different from ClpA, ClpX and HslU as it does not associate with peptidase subunits. The function of ClpB is also distinct from that of other Clp ATPases: this protein is not involved in protein degradation, instead it disaggregates and reactivates strongly aggregated proteins. The aggregation reversing activity of ClpB requires cooperation with the HSP70/HSP110 chaperone machinery.

Structured Information

Detailed analysis of the amino acid sequence has revealed that Hsp100 members contain several conserved signatures. Schirmer et al divided Hsp100 into class I (Hsp100 types A–D; containing two nucleotide-binding domains) and class II (Hsp100 types M, N, X, and Y; containing one nucleotide-binding domain) proteins. The molecular weights of the Hsp100 proteins is considered to vary between 75 and 100 kDa because of the size of the non-conserved spacers between the 2 domains and additional sequences at the Cand N-termini. Basically, Hsp100 proteins are composed of fi ve specifi c domains as follows: (i) amino (N) - terminal domain, (ii) nucleotide – binding domain 1 (NBD1), (iii) middle domain, (iv) NBD2 and (v) carboxyl (C) - terminal domain. The conserved sequences of the fi ve domains include (i) signature sequence I in the N-terminal domain, (ii) Walker A, Walker B1, and Walker B2 sequences in the NBD1, (iii) signature sequence II and signature sequence III in the middle domain, (iv) Walker A and Walker B sequences in NBD2 and (v) signature sequence IV and V in the C-terminal domain. Based on more extensive analysis with larger spectrum of plant species, Agarwal et al reported further specifi c alterations in the amino acid sequence of various motifs of plant Hsp100 members.
