Primary antibody notes
A recently identified protein, termed carboxyl terminus of hsc70-interacting protein (CHIP), has been shown to interact both with the constitutive form of hsc70 and the stress inducible form, hsp70. This novel 35 kDa cytoplasmic protein has been shown to be highly expressed in striated muscle in vivo. Additional studies have shown that this protein is expressed over a broad range of cultured tissues. Through immunoprecipitation experiments, CHIP has been shown to directly bind to the carboxyl terminus of hsc70 and hsp70 where it decreases ATPase activity and reduces overall chaperone efficiency. CHIP has also been identified as an important protein in the ubiquitin-proteasome system. CHIP contains a U-box domain and acts as an E3 ubiquitin-ligase in conjunction with hsc70 and hsp90. -

Function
E3 ubiquitin-protein ligase which targets misfolded chaperone substrates towards proteasomal degradation. Ubiquitinates NOS1 in concert with Hsp70 and Hsp40. Modulates the activity of several chaperone complexes, including Hsp70, Hsc70 and Hsp90. Mediates transfer of non-canonical short ubiquitin chains to HSPA8 that have no effect on HSPA8 degradation. Mediates polyubiquitination of DNA polymerase beta (POLB) at 'Lys-41', 'Lys-61' and 'Lys-81', thereby playing a role in base-excision repair: catalyzes polyubiquitination by amplifying the HUWE1/ARF-BP1-dependent monoubiquitination and leading to POLB-degradation by the proteasome. Mediates polyubiquitination of CYP3A4. -
Tissue specificity
Highly expressed in skeletal muscle, heart, pancreas, brain and placenta. Detected in kidney, liver and lung. -
Pathway
Protein modification; protein ubiquitination. -
Sequence similarities
Contains 3 TPR repeats.
Contains 1 U-box domain. -
Domain
The TPR domain is essential for ubiquitination mediated by UBE2D1. -
Post-translational
modificationsPhosphorylated upon DNA damage, probably by ATM or ATR.
Auto-ubiquitinated; mediated by UBE2D1 and UBE2D2. -

Western blot - Anti-STUB1/CHIP antibody (ab2917)
Western blot detection of transfected COS-1 cells expressing STUB1/CHIP using ab2917.
-
Western blot - Anti-STUB1/CHIP antibody (ab2917)Western blot analysis of STUB1/CHIP was performed by loading 20ug of total protein extracted from the left hemisphere (Left lane) or right hemisphere (right lane) of a normal C57BL/6 mouse brain per well on an SDS-PAGE gel. Proteins were transferred to a membrane, blocked with 5% non-fat dry milkand probed with a STUB1/CHIP polyclonal antibody (ab2915) at a dilution of 1:1000, followed by a HRP-conjugated goat anti-rabbit IgG secondary antibody. Detection was performed using a chemiluminescent substrate.
