The higher molecular form may represent an insoluble dimer, as this has previously been reported for the apyrase of Triatoma infestans [ 151].
Interestingly, in CoPP-treated cells, the accumulated Sqstm1 appeared only in the expected monomeric (62 kDa) form, whereas higher molecular forms that likely represent oxidized and crosslinked protein were found in heme-treated cells.
Classification of chromosomal arm 2R karyotypes by multilocus genetic clustering identified two clusters loosely corresponding to molecular forms, with 'mismatches' representing admixed individuals due to shared ancestral polymorphism and/or residual hybridization.
In transfected HEK293 cells, wild-type DDR2 is usually observed as a mixture of three (sometimes four) molecular weight forms between ∼125 and 130 kDa (5, 21, 22), with the upper forms representing complex glycosylated mature forms.
For example A. gambiae exhibits variably-permeable species boundaries, particularly between the M and S molecular forms, which are thought to represent incipient species [22].
Although several studies have strongly suggested that the molecular forms of PSA seem to represent a potential tool for the risk assessment of breast cancer, recent reports have yielded conflicting results.
Third, since the molecular forms of An. gambiae represent a more recent realization of an ongoing speciation process, with the M-form likely being most recently derived [ 8, 10], we predict that the M-form should occur in more marginal habitats than the other two taxa, in accordance with a process of niche expansion from the original, optimal habitat [[ 44], for an example, see [ 45]].
A composite of "all" Culture-derived Molecular Analysis T-RF bands was formed representing the species detected on all types of media.
This also illustrates that mosquitoes typed as M/S heterozygotes in our study generally do not represent F1 hybrids between the molecular forms, but are members of a thoroughly backcrossed and homogenized population, together with S/S homozygotes.
(representing two incipient species known as the M and S molecular forms), a sibling species An. arabiensis, and An.
