Human
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Pro150 of human OCA-T1 protein.
Background
OCA-T1 is encoded by the gene POU2AF2 (C11orf53), which was identified in a single-cell RNA sequencing study to be expressed selectively in tuft cells from mouse and human tissues (1). The expression of OCA-T1 was observed to occur in a pattern strikingly similar to that of POU2F3, a master regulator of tuft cell development whose expression also defines a tuft cell-like variant (SCLC-P) of small cell lung cancers (2). Although containing no recognizable structural domains, OCA-T1 showed minor sequence similarity with OCA-B, a protein encoded by the POU2AF1 gene and reported to be an activator of selected Class II POU domain transcription factors (3). Functional studies revealed that OCA-T1 forms a protein complex with POU2F3; these proteins furthermore share genomic binding sites and promote the expression of genes directly associated with tuft cell development. Lastly, Crispr/Cas9-mediated deletion of POU2AF2 in mice revealed that OCA-T1 is functionally required for normal tuft cell development (1). Collectively, these findings suggest that OCA-T1 is a critical component of the POU2F3-containing transcriptional complex that regulates the expression of genes governing tuft cell development.
Species Reactivity
Species reactivity is determined by testing in at least one approved application (e.g., western blot).
Western Blot Buffer
IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
