Anti-Tctex5 antibodies are used in antigen-specific immunodetection in biological samples. The target Tctex5 is a known alias name of the protein protein phosphatase 1 regulatory inhibitor subunit 11, encoded by the PPP1R11 gene in humans. This 126-amino acid residue protein is known to be involved in cytokine-mediated signaling pathways and protein ubiquitination, among other biological processes. In terms of tissue expression, it is widely expressed across many tissue types. Other synonyms for Tctex5 include CFAP255, HCG-V, and HCGV.
