Epidermal Langerhans cells (LCs) have been believed to function as professional antigen-presenting cells (APCs).
Amelogenin proteins, the principal components of the developing dental enamel matrix, self-assemble to form nanosphere structures that are believed to function as structural components directly involved in the matrix mediated enamel biomineralization.
The tumor suppressor p14ARF is widely deregulated in many types of cancers and is believed to function as a failsafe mechanism, inhibiting proliferation and inducing apoptosis as cellular response to a high oncogene load.
CRT is one of the 'eat me' signals, which is often thought to localize in the lumen of the endoplasmic reticulum (ER), but was also found on the plasma membrane of apoptotic cancerous cells (Fig. 1), where it is believed to function as an 'eat me' signal2 and a damage-associated molecular pattern (DAMP) responsible for the immunogenicity of apoptotic cancerous cells3.
These structures are believed to function as the new third route for the Sn diffusion.
In both cases, the peptides were believed to function as both the reducing and protection agents.
Furanocoumarins are believed to function as phytoalexin (Beier and Oertli 1983) or allelochemical compound (Baskin et al. 1967).
In fact, Rho GTPases such as ROP1 and interacting protein RIC3 are believed to function as spatial regulators of ABPs including F-actin, profilin and formin and thus help determine growth polarity (Chebli et al. 2013; Cheung et al. 2010).
The proteins of the ABC transporter family are believed to function as drug efflux pumps and increased levels of these proteins in CSCs could therefore be contributing to the protection of CSCs from cytotoxic chemotherapy [30]-[33] [30]-[33]
Police returned on Tuesday with a search warrant, and recovered a "coin pusher" machine -- also believed to function as a slot machine.
Initially, resveratrol was believed to function as an antioxidant.
