Our results indicate that comparative microsynteny-based mapping can facilitate positional cloning of a target gene when information on genomic location is limited.
As part of a positional cloning project, we became interested in a region of 5q31 between D5S393 and D5S2927.
Cell lines were created by incorporation of retroviral vectors into the genome and expression of Tag from either the retroviral LTR (considered to be a strong promoter) or the herpes virus thymidine kinase promoter, internal to the viral LTR [ 1 ] . In our established NIH 3T3 cell line, Tag is expressed from the htk promoter at considerably lower levels than from the LTR for a considerable time after transduction [unpublished observations, and [ 11 ] ]. However, when a large number of htk-Tag astrocyte clones were checked 100 days after creation, the expression levels displayed a very large range, and thus we expect that this weak promoter is subject to positional effects on transcription or mutational events that affect gene expression (unpublished data).
Objects in nuclei recognized by antibodies specific for phosphoprotein epitopes, cytoplasmic IFs, or both, have been reported in glial and neuronal cells, in situ and in vitro . The nuclear structures appear spherical or rod-like and may have a positional relationship with nuclear pores [ 1 2 3 4 ] . Morphologically, these structures appear similar to the nuclear "speckles" that are thought to be storage sites for RNA splicing factors [ 5 6 7 ] . However, while intermediate filament (IF) phosphoproteins could be components of nuclear speckles, they are immunologically distinct.
13 suggested some positional effect variegation (PEV) of the transgene, an effect not previously reported in trangenes that include the entire CD2 LCR [ 17 18 ] . Further, we have noticed that the percentage of hCARΔcyt positive T cells in the line hCARΔcyt.CD2.
