Kinesin dimer/David S. Goodsell, Scripps Research Institute
Two intertwined chains with globular heads on one end form a Kinesin dimer.
The activity of HIF-1 dimer, which is composed of α and β subunits, is modulated by the availability of the extremely labile oxygen-sensitive HIF-1α protein subunit.
SDS-PAGE, PknJ forms stable dimer, which is also shown by variants PknJ-KD-K43A and
In this study, Lidke and her colleagues showed that that protein pairing - known as dimer formation - is, in fact, not necessary for ERK to move into the nucleus after all.
The opposite ends of the dimer drag the cargo along that they are attached to.
If you believe PE or DVT is a reasonable diagnosis to pursue,testing should be done even if the Wells rule suggests low risk or unlikely and the d-dimer is negative.show me a blood test that can't be wrong. posted by james gaulte @ 3:44 AM
In the first two instances, one then proceeds to obtain a highly sensitive D-dimer test e.g.,enzyme-linked immunosorbent assay.
I think a better reason not to rely on the D-dimer a high probability case is , is concern that a potentially fatal condition may be missed because of one erroneous negative biological lab test considering all the many ways lab tests can get screwed up.
Interestingly, when one reviews the quoted reference in the Archives of Internal Medicine for that advice it turns out the study involved only 13 instances of high probability PE cases all of whom had a elevated d-dimer.
