Protein PSK SIMULATOR
InterPro entry
Short name | PSI1/2/3 |
Description
This family represents the plant-specific proteins PSI 1-3 (Protein PSK SIMULATOR 1-3) from Arabidopsis. These proteins promote plant growth, especially at the vegetative stage, probably via the regulation of phytosulfokine (PSK) signalling; PSKs are peptide phytohormones acting as growth factors
[1]. They are required during vegetative growth and reproduction, PSI1 acts predominantly at the seedling stage whereas PSI2 and 3 are required for vegetative growth where they act synergistically. PSI1 and 3 may also have a function in carbohydrate metabolism
[1].
