FLN-2 is expressed in the hypodermis including the main body syncytium
hyp7 and the smaller head and tail hypodermal cells. In
hyp7, FLN-2::GFP shows both vesicular and parallel stripe-like patterns. FLN-2::GFP co-localizes with VHA-5::RFP on the vesicular structures. The parallel stripe- like pattern of FLN-2 overlaps with VAB-10A, a component of the epidermal attachment structures called fibrous organelles (FOs), which suggests that FLN-2 also localizes to the FOs (Zhang and Labouesse, 2010). FLN-2 is also expressed in the kidney-like excretory canal cell, which is important for osmoregulation (Liegeois et al., 2006; Sundaram and Buechner, 2016). In the excretory canal, FLN-2::GFP is aligned at the apical side of VHA-5::RFP.
