description: This entry represents the N-terminal domain of PSI proteins from Arabidopsis. This domain
  is found associated with [pfam:PF05003]. PSI1 was identified as a gene that is co-expressed with the
  phytosulfokine (PSK) receptor genes PSKR1 and PSKR2 in Arabidopsis thaliana. PSI proteins are plant-specific
  and promote growth [[cite:PUB00093967]].
