Such findings are in excellent agreement with previous observations that molecules in cellular membranes can remain mobile under certain, relatively mild PFA fixation conditions [12].
If there is a barrier to diffusion at any given location, it will require a longer time to find the particle at a position across the barrier, as demonstrated for the diffusion of molecules in cellular membranes [19].
Recently, circuit diagnosis techniques have been utilized to identify the most vulnerable molecules in cellular networks [ 31].
While the roles of adhesion molecules in cellular recruitment have been partially defined [15], their relative abilities to mediate binding of antibody-conjugated inert particles is unexplored.
Retinoids (compounds including vitamin A and its synthetic and naturally occurring analogs) are key molecules in cellular proliferation and differentiation [ 8].
The identified antisense transcripts in U. maydis provide a starting point for uncovering new roles for these molecules in cellular function.
