Through selective degradation of Clp subunits, AtCHIP could positively regulate homeostasis of Clp proteolytic subunits and maximize the production of functional chloroplasts. Similar results were obtained from transgenic tobacco plants.
Title: The E3 ligase AtCHIP positively regulates Clp proteolytic subunit homeostasis.

we propose that CHIP and NBR1 mediate two distinct but complementary anti-proteotoxic pathways and protein's propensity to aggregate under stress conditions is one of the critical factors for pathway selection of protein degradation
Title: E3 ubiquitin ligase CHIP and NBR1-mediated selective autophagy protect additively against proteotoxicity in plant stress responses.

Hsc70-4 and CHIP were highly induced in ppi2 mutant plants, where they mediated the degradation of chloroplast-targeted precursors through the ubiquitin-26S proteasome system.
Title: Heat shock protein cognate 70-4 and an E3 ubiquitin ligase, CHIP, mediate plastid-destined precursor degradation through the ubiquitin-26S proteasome system in Arabidopsis.

The interaction of CHIP with FtsH1 in vitro, in normal and in CHIP-over-expressing plants is reported.
Title: The E3 ligase AtCHIP ubiquitylates FtsH1, a component of the chloroplast FtsH protease, and affects protein degradation in chloroplasts.

AtCHIP, an E3 ubiquitin liagase, functions upstream of protein phosphatase 2A in stress-responsive signal transduction pathways under conditions of low temperature or in the dark. [AtCHIP]
Title: AtCHIP functions as an E3 ubiquitin ligase of protein phosphatase 2A subunits and alters plant response to abscisic acid treatment.
