Also known as: CG5203; Chip; CHIP; dCHIP; Dmel\CG5203; Stub1
Summary: Enables ubiquitin protein ligase activity. Involved in negative regulation of insulin receptor signaling pathway; positive regulation of proteolysis; and protein ubiquitination. Colocalizes with Z disc. Is expressed in adult head; eye; and organism. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 16 and cerebellar ataxia type 48. Orthologous to human STUB1 (STIP1 homology and U-box containing protein 1). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Taken together, our findings identified Chip as a novel partner of dLmx1a to alter cell differentiation in Drosophila eye through repressing eya and stg expression
Title: Drosophila eye developmental defect caused by elevation of the activity of the LIM-homeodomain protein, Lmx1a, requires its association with the Co-activator Chip.
study reveals that Chip is a novel interacting partner of Notch
Title: Chip physically interacts with Notch and their stoichiometry is critical for Notch function in wing development and cell proliferation in Drosophila.
Data have found that the transcriptional co-factor Chip is required for cells at the ventral eye-antennal disc border to take on a head cuticle fat
Title: The transcriptional co-factor Chip acts with LIM-homeodomain proteins to set the boundary of the eye field in Drosophila.
