Alternatives: "although not necessary" or "even if not crucial".
Binding of this mutant, however, was impaired for the C-terminus SE fragment, possibly suggesting that LxCxE region, albeit not essential, might still participate in binding.
Gab2 plays an important albeit not essential role in the development of various haematopoietic lineages [ 113], except for NK cells [ 148].
On the other hand, we have found that albeit p57 is phosphorylated, it is not essential for cell survival in response to UV.
The ability of osteopontin-null muscles to eventually undergo muscle fibre necrosis and regeneration, albeit delayed, suggests that osteopontin is not essential for muscle repair, possibly due to compensation for the loss of osteopontin by other unidentified proteins (Boudiffa et al., 2010; Monfoulet et al., 2010).
We proved that the C-terminal repeats are not essential for TcdA function albeit they determine the potency of the toxin by interacting with surface structures of host cells.
The current study proved that the C-terminal repeats (CROPs) of TcdA and TcdB are not essential for the toxins biological function, albeit determining the potency of the toxin by their interactions with cell surface structures.
We found that Tfh cells were generated following immunization of IL-6Rα T-KO mice, albeit at moderately reduced frequencies, suggesting that IL-6 is not essential as an instructive signal for the induction of this T cell lineage.
While Kras4B is ubiquitously expressed, albeit at varying levels across tissues, Kras4A expression is tissue-specific and not essential for embryonic development, suggesting that Kras4A has a minor role in Kras biology.
Albeit not a very good one.
Overall: fun, if not essential.
