NCBI Protein Information
Chaperone protein htpG family protein
NCBI Summary
encodes an ortholog of GRP94, an ER-resident HSP90-like protein and is involved in regulation of meristem size and organization. Single and double mutant analyses suggest that SHD may be required for the correct folding and/or complex formation of CLV proteins. Lines carrying recessive mutations in this locus exhibits expanded shoot meristems, disorganized root meristems, and defective pollen tube elongation. Transcript is detected in all tissues examined and is not induced by heat. Endoplasmin supports the protein secretory pathway and has a role in proliferating tissues.

UniProt Comments
May have a molecular chaperone role in the processing of secreted materials. Required for shoot apical meristem (SAM), root apical meristem (RAM) and floral meristem (FM) formation, probably by regulating the folding of CLAVATA proteins (CLVs). Also involved in pollen tube elongation (PubMed:11867518). Involved in resistance to tunicamycin- or high calcium-induced ER stresses. Possesses ATPase activity (PubMed:25297550).
