Function

[VASA1_DROME] Involved in translational control mechanisms operating in early stages of oogenesis. Required maternally in many stages of oogenesis, including cystocyte differentiation, oocyte differentiation, and specification of anterior-posterior polarity in the developing cysts. Essential for the formation and/or structural integrity of perinuclear nuage particles during germ cell formation. Required for gus, Fsn and aub accumulation at the posterior pole of the embryo. Required for the localization of vas to the perinuclear region of nurse cells.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] ^[10] ^[11] [OSKA_DROME] Organizes the germ plasm and directs localization of the posterior determinant nanos. Oskar protein is required to keep nos RNA and staufen protein at the posterior pole.^[12] ^[13] ^[14]

Publication Abstract from PubMed

DEAD-box RNA helicases play important roles in a wide range of metabolic processes. Regulatory proteins can stimulate or block the activity of DEAD-box helicases. Here, we show that LOTUS (Limkain, Oskar, and Tudor containing proteins 5 and 7) domains present in the germline proteins Oskar, TDRD5 (Tudor domain-containing 5), and TDRD7 bind and stimulate the germline-specific DEAD-box RNA helicase Vasa. Our crystal structure of the LOTUS domain of Oskar in complex with the C-terminal RecA-like domain of Vasa reveals that the LOTUS domain occupies a surface on a DEAD-box helicase not implicated previously in the regulation of the enzyme's activity. We show that, in vivo, the localization of Drosophila Vasa to the nuage and germ plasm depends on its interaction with LOTUS domain proteins. The binding and stimulation of Vasa DEAD-box helicases by LOTUS domains are widely conserved.

The LOTUS domain is a conserved DEAD-box RNA helicase regulator essential for the recruitment of Vasa to the germ plasm and nuage.,Jeske M, Muller CW, Ephrussi A Genes Dev. 2017 May 1;31(9):939-952. doi: 10.1101/gad.297051.117. Epub 2017 May, 23. PMID:28536148^[15]
