Cellular location

I) HSP100

a) AtTCP-1 / GroEL, GroES

i) Cytosol

II) HSP90

b) Various AtHSP22, AtHSP20, AtHSP18.2, AtHSP17.6 / IBPA/B

ii) mitochondria

III) HSP70

c) AtHSP101 / ClpB, ClpA/C

iii) chloroplasts

IV) HSP60

d) AtHSP70 / DnaK

iv) endoplasmic reticulum

V) smHSP

e) AtHSP90 / HtpG
