Analysis Note

ControlK562 cell lysate

Application

Western Blotting Analysis: 1 µg/mL from a representative lot detected WAC in 10 µg of HEK293 cell lysate.

Immunoprecipitation Analysis: A representative lot from an independent laboratory detected WAC, N-terminus in 293T cell lysates stably transfected with SFB-RNF20 and in HCT116 cell lysates transfected with siRNA negative control (Zhang, F. and Yu, X. (2011). Mol Cell. 41(4):384-397.).

Chromatin Immunoprecipitation: A representative lot from an independent laboratory detected WAC, N-terminus in HCT116 cell lysates transfected with siRNA negative control, but demonstrated a loss of signal in HCT166 cell lysates transfected with siRNF20 (Zhang, F. and Yu, X. (2011). Mol Cell. 41(4):384-397.).

Anti-WAC, N-terminus detects levels of WAC proteins & has been published & validated for use in WB, IP & ChIP.

General description

WAC (WW domain-containing adapter protein with coiled-coil) functions as a linker between gene transcription and histone H2B monoubiquitination at ′Lys-120′ (H2BK120ub1). Wac interacts with the RNA polymerase II transcriptional machinery through its WW domain and with RNF20-RNF40 via its coiled-coil region. It has been shown to regulate H2BK120ub1, gene transcription, cell-cycle checkpoint activation in response to DNA damage, positively regulate amino acid starvation-induced autophagy and negatively regulate the ubiquitin proteasome pathway. In nuclear speckles it has been observed to colocalize with pre-mRNA processing complexes. This antibody recognizes the N-terminus of the WAC protein.

Immunogen
