Ellis van Creveld syndrome and Weyers acrofacial dysostosis are two rare genetic diseases affecting skeletal development. They are both ciliopathies, as they are due to malfunction of primary cilia, microtubule-based plasma membrane protrusions that function as cellular antennae and are required for Hedgehog signaling, a key pathway during skeletal morphogenesis. These ciliopathies are caused by mutations affecting the EVC-EVC2 complex, a transmembrane protein heterodimer that regulates Hedgehog signaling from inside primary cilia. Despite the importance of this complex, the mechanisms underlying its stability, targeting and function are poorly understood. To address this, we characterized the endogenous EVC protein interactome in control and Evc-null cells. This proteomic screen confirmed EVC’s main known interactors (EVC2, IQCE, EFCAB7), while revealing new ones, including USP7, a deubiquitinating enzyme involved in Hedgehog signaling. We therefore looked at EVC-EVC2 complex ubiquitination. Such ubiquitination exists but is independent of USP7 (and of USP48, also involved in Hh signaling). We did find, however, that monoubiquitination of EVC-EVC2 cytosolic tails greatly reduces their protein levels. On the other hand, modification of EVC-EVC2 cytosolic tails with the small ubiquitin-related modifier SUMO3 has a different effect, enhancing complex accumulation at the EvC zone, immediately distal to the ciliary transition zone, possibly via increased binding to the EFCAB7-IQCE complex. Lastly, we find that EvC zone targeting of EVC-EVC2 depends on two separate EFCAB7-binding motifs within EVC2’s Weyers-deleted peptide. Only one of these motifs had been characterized previously, so we have mapped the second herein. Altogether, our data shed light on EVC-EVC2 complex regulatory mechanisms, with implications for ciliopathies., Peer reviewed

8 figures, 4 tables.-- Under the CC-BY-NC-ND 4.0 license https://creativecommons.org/licenses/by-nc-nd/4.0/, Trassatti’s method.-- Supplementary tables.-- Supplementary figures.-- Trassatti’s method: In Trassatti’s method, the charge (q) in the voltammetry test is assumed to depend on the scan rate (υ) as follows:
q=q_∞+a_1 υ^(-1/2) (S1)
1/q=1/q_T +a_2 υ^(1/2) (S2)
where a_1 and a_2 are constants, q_∞ is the charge not limited by ion diffusion (υ→∞), and q_T is the total cell charge (υ→0). If the measurements are carried out under the same conditions, they can be applied in terms of capacitance as follows:
C_((υ))=a_1 υ^(-1/2)+ C_EDL (S3)
1/C_((υ)) =a_2 υ^(1/2)+ 1/C_T (S4)
where C_EDL is the capacitance arising from the electric double-layer (not limited by ion diffusion) and C_T is assumed to be the total capacitance, such as:
C_T=C_PsC+C_EDL (S5)
where C_PsC is the capacitance arising from Faradaic contributions.

6 files, This dataset consists of the estimated decadal changes in the oceanic content of anthropogenic CO2 (∆Cant) between 1994, 2004 and 2014 as described in detail in Müller et al. (2023, in press, AGU Advances). These estimates have been derived from the GLODAPv2.2021 product (Lauvset et al., 2021) using the eMLR(C*) method developed by Clement & Gruber (2018). The datasets contain in addition to the standard estimate also 10 sensitivity cases, which are intended to assess the robustness of the standard estimates to different changes in the estimation procedure. All estimates are provided on a horizontal grid with 1° x 1° resolution. Two primary files are provided: one containing the full three-dimensional distribution of ∆Cant and one containing the vertically integrated values, i.e., the column inventories, 821003 - Climate-Carbon Interactions in the Coming Century (EC); 821001 - Southern Ocean Carbon and Heat Impact on Climate (EC), Peer reviewed
