Enables primary miRNA binding activity. Involved in positive regulation of NLRP3 inflammasome complex assembly and stress granule assembly. Acts upstream of or within with a negative effect on primary miRNA processing. Located in cytoplasmic stress granule. Part of NLRP3 inflammasome complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in syndromic X-linked intellectual disability. Orthologous to human DDX3X (DEAD-box helicase 3 X-linked). [provided by Alliance of Genome Resources, Apr 2022]
