Praja1, RING-H2 motif containing

Praja1, PJA1
This gene encodes an enzyme that has E2-dependent E3 ubiquitin-protein ligase activity. This enzyme belongs to a class of ubiquitin ligases that include a RING finger motif, and it can interact with the E2 ubiquitin-conjugating enzyme UbcH5B. This gene is located in an area of chromosome X where several X-linked mental retardation disorders have been associated, and it has also been found as part of a contiguous gene deletion associated with craniofrontonasal syndrome, though a direct link to any disorder has yet to be demonstrated. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010] (from NCBI)

We have confirmed these data by showing that an ICP4-expressing plasmid will downregulate lacZ expression from a plasmid containing the LAT promoter and transcription start site (pJA1) and does not downregulate lacZ expression from a plasmid in which the start site has been mutagenized (pWAG15).
