Gene Information

Gene Detail

Gene Symbol: Sumo3
Name: SMT3 suppressor of mif two 3 homolog 3 (yeast)
Alteration at locus: Gene Trap
Chromosome: 10

Genetic Alterations:
High throughput gene trapping was performed by inserting a gene trap vector containing a splice-acceptor sequence upstream of a reporter gene, β-geo (a fusion of β-galactosidase and neomycin phosphotransferase II), into an intronic or coding region of genomic DNA. The resulting insertional mutation creates a fusion transcript containing sequences from exons upstream of the insertion joined to the β-geo marker, allowing cell lines where the vector has successfully interrupted a gene to be identified.

Parental ES Cell Line: E14Tg2a.4 (MMRRC Stock Number 015890-UCD)

Special Considerations

When choosing a clone, we recommend blasting the sequence tag to estimate the location of a gene trap. Generally you will want to select a clone that traps the furthest upstream. The vast majority of gene trap cell lines have been correctly identified, as judged by DNA sequencing (i.e., repeat determination of the DNA sequence tag when the ES cell clone is requested). However, incorrectly identified ES cell clones are occasionally encountered, either because of human error or because a thawed ES cell line gets overgrown by a contaminating ES cell line. Therefore, we strongly recommend that you request verification of the identity of your ES cell line by DNA sequencing (there is an additional fee for DNA sequence verification of your clone). We also recommend that recipients of ES cells re-verify the identity of the ES cell line by RT-PCR and/or Southern blot analysis. If more than one ES cell line is available for your "gene-of-interest", we recommend that you order several of the ES cell lines. Ordering more than one ES cell line for a specific "gene-of-interest" will increase the chances of success.

Health Status Report

Requested cell lines are tested by PCR analysis for mycoplasma spp. and Murine Parvoviruses (MPV) upon completion of expansion and prior to shipment. The parental cell line E14Tg2a.4, from which these cells were derived, was tested for multiple mouse pathogens; please see the Health Status Report. Mice derived from requested cell lines via Microinjection services will be pathogen tested prior to delivery of mice and health reports will be provided. If you require additional health status information prior to requesting microinjection please email

Availability Level

Cryo-preserved ES cell line material can usually be shipped in 2 to 4 weeks. Genetic confirmation adds an additional 4 to 6 weeks (but is recommended to confirm that the material has not been contaminated or otherwise incorrectly identified). The microinjection services add an additional 10 to 12 weeks and can vary from cell line to cell line.

Conditions of Distribution

Please complete the Sanger Institute Gene Trap MTA. This document must be signed by an authorized Technology Transfer representative from your institution. Please provide two signed originals, mailed to the address located on page 2 of the MTA. The MTA will be counter-signed by a designated representative from the MMRRC, and a fully executed copy returned to your institution. Your request will be processed upon receipt of the signed MTA at the appropriate MMRRC center.


Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.
