The phrase "a broad range of cellular functions" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in biology or medicine, to describe the diverse activities and roles that cells perform.
Example: "The study revealed that the protein plays a crucial role in regulating a broad range of cellular functions, including metabolism and cell signaling."
Alternatives: "a wide variety of cellular activities" or "a diverse array of cellular processes."
This established, they examined a broad range of cellular functions, eventually discovering the role that ion channels play in such diseases as diabetes, cystic fibrosis, epilepsy, several cardiovascular diseases, and certain neuromuscular disorders.
This delicate balance is important as Wnt pathway transcriptional activity influences a broad range of cellular functions.
Novel findings were the marked expression of different isoforms in the caveolin, synaptotagmin, and tropomodulin families (Figure 3A), suggesting that muscle cells express specific isoforms also for proteins with a broad range of cellular functions.
This data suggest that KIAA1199 may affect a broad range of cellular functions.
An analysis of these interactors implicates PDZ domains in a broad range of cellular functions.
CD81 is involved in a broad range of cellular functions as revealed by the binding of monoclonal antibodies.
It is involved in several signaling cross-talks with caspases and functions as a pivotal mediator in a broad range of cellular processes such as apoptosis and inflammation.
Notably several heat shock and DnaJ proteins are shared across the functions of hormone binding and ER stress, suggesting that a broad range of cellular changes are mediated by chaperones.
More recent findings have shown that LDL receptor family members can also function as direct signal transducers or modulators for a broad range of cellular signalling pathways.
Their detailed molecular function is still under debate; however, they influence a broad range of cellular processes, including translation, transcription and autophagy [ 24, 26, 27, 28].
Megakaryoblastic leukaemia 1/2 proteins (MKL1/2) function as coactivators of the transcription factor serum response factor (SRF) that regulates a broad range of cellular processes such as organization of the cytoskeleton, cell migration, cell growth and differentiation (Pipes et al, 2006).
