SF Pontin52 binds direct to beta-catenin in the region of Armadillo repeats 2-5 and to the TBP (TATA box binding) protein (the name comes from pons, bridge in Latin);
SF seems to build up a multiprotein complex with beta-catenin and TCF/ LEF transcription factors;
SF localized in the nucleus;
SF does not bind to LEF/ TCF directly [1];
XX
CP appears to be rather ubiquitously expressed [1].
XX
FF there is good evidence that Pontin52 bridges the LEF-1/ beta-catenin complex to TBP (TATA box binding protein) and thus to the basic transcriptional machinery;
FF on wnt/ wg signaling pontin 52 could thus function as a coactivator in regulating the expression of target genes [1];
