You will be given a definition of a task first, then some input of the task.
In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.

Ca 2+ is one of the most universal and versatile signaling molecules and is involved in almost every aspect of cellular processes. Viruses are adept at utilizing the universal Ca 2+ signal to create a tailored cellular environment that meets their own demands. This review summarizes most of the known mechanisms by which viruses perturb Ca 2+ homeostasis and utilize Ca 2+ and cellular Ca 2+ -binding proteins to their benefit in their replication cycles. Ca 2+ plays important roles in virion structure formation, virus entry, viral gene expression, posttranslational processing of viral proteins and virion maturation and release. As part of the review, we introduce an algorithm to identify linear "EF-hand" Ca 2+ -binding motifs which resulted in the prediction of a total of 93 previously unrecognized Ca 2+ -binding motifs in virus proteins. Many of these proteins are nonstructural proteins, a class of proteins among which Ca 2+ interactions had not been formerly appreciated. The presence of linear Ca 2+ -binding motifs in viral proteins enlarges the spectrum of Ca 2+ -virus interplay and expands the total scenario of viral calciomics. (J.J. Yang). for structural integrity or functionality; and (3) critical virus-host interactions depend on cellular Ca 2+ -regulated proteins or pathways. This review, which aims to stimulate future studies on the roles of Ca 2+ in virus infection, is focused on such interplay by highlighting recent discoveries in the biological roles of Ca 2+ in virus infection. 0143-4160/$ -see front matter
