                      MISC: GAPDH pseudogene?

We are performing RT-PCR on some human tissue samples and have made
primers to GAPDH as a positive control.  These primers are from the
first and fith exons, therefore they should generate about a 320 bp
band when amplifying fully processed mRNA (cDNA) or a 2.2 Kb band when
amplifying genomic DNA. However, when we perform PCR on human genomic
DNA we obtain a 320 bp band.  We believe we have eliminated the
possibility that the DNA is contaminated  by RNA or the possibility
that the PCR reaction (reagents) is contaminated.  At this time we
believe the only other explanation is that the human genome has a
pseudogene for GAPDH.   We have checked the Genbank databases and find
no evidence for a GAPDH pseudogene.

Has anyone else ever experienced this same (or similar) problem?

Is there any evidence for a GAPDH pseudogene?

Thank you for any comments/suggestions.

Dear everyone,

I am interested to find out more about methylation sensitive RDA. Any
information would be much appreciated. Thank you very much.

Dear Colleagues,

We have a gene with high similarity to subunits of Ca+2-activated
potassium channels on chromosome 3. Would someone be interested to
collaborate with us on further mapping and characterization of this

    Are any laboratories currently doing LDL binding activity assays
on cultured fibroblasts or amniocytes?

We are looking for RNAs and high-molecular-weight DNAs from
early endometrial premalignant lesions as well as frank endometrial
tumors. They should be of relatively high (50% or greater) neoplastic
cell purity.

Please email smeltzer@umabnet.ab.umd.edu.

Thank you.

Defects in Facc are the cause of one of the four
complementation groups of Fanconi Anemia (FA).
Does anybody know if an antibody against human Facc
protein has been isolated and characterized?
