Example: "The protein is assumed to function in cellular signaling pathways, influencing various biological processes."
Alternatives: "expected to operate in" or "believed to play a role in".

These isoforms were assumed to function in the adaption to different oxygen environments.
Nevertheless they are assumed to function in a similar manner as NPM ALK.
Homologous genes for FtsZ and DRP5B have been found in some secondary plastid-bearing algae, heterokonts and a haptophyte, and these proteins are assumed to function in the constriction of the inner pair of four plastid membranes [ 11].
The ntPPO2 α5, which forms a dimer interface at the base of membrane-binding domain in the crystal structure, is assumed to function in dimerization and/or interaction with membrane lipids (Koch et al. 2004).

These meiotic cohesin complexes are assumed to function not only in sister chromatid cohesion, but also in specialized chromosomal events in meiotic progression such as axial element formation, homologue pairing and the assembly/disassembly of synaptonemal complex.
Although Baz/PAR-3, PAR-6, and aPKC are often assumed to function as a complex in epithelial cells, there is increasing evidence that Baz/PAR-3 acts independently from PAR-6 and aPKC in this cell type.
Most HsfBs, except HsfB5, contain the tetrapeptide LFGV in the C-terminal domain, which is assumed to function as a repressor motif in the transcriptional machinery [ 8].
