Recombinant Arabidopsis thaliana HVA22-like protein d, commonly referred to as HVA22D, is a protein derived from the model plant Arabidopsis thaliana. This protein is part of the HVA22 family, which plays significant roles in plant responses to abiotic stresses and hormonal regulation. HVA22D is homologous to a barley gene that is induced by abscisic acid (ABA) and involved in stress responses and programmed cell death regulation.
Protein Structure and Function: HVA22D is a protein with specific structural features that allow it to interact with cellular components involved in stress responses and cellular regulation. It is localized in the endoplasmic reticulum (ER) and Golgi apparatus, similar to its barley counterpart, HVA22 .
Expression and Regulation: The expression of HVA22D is influenced by environmental stresses and hormonal signals. It is part of a larger family of genes that respond to drought, salt, and cold stresses, among others .
Production and Availability: Recombinant HVA22D is available in various forms, including full-length and partial proteins, produced in different expression systems such as yeast, E. coli, and mammalian cells .
