Table 2 CA expression patterns of CAs in S. ciliatum

From: Calcareous sponge genomes reveal complex evolution of α-carbonic anhydrases and two key biomineralization enzymes

CA ISH RNA-Seq
SciCA1 (scl-CA1) Sclerocytes, weak signal in ring of posterior-most micromeres in larvae All stages (including spicule-free larva and postlarval stage i), higher expression in top region of sponge
SciCA2 (scl-CA2) Sclerocytes, weak signal in ring of posterior-most micromeres in larvae All stages (including spicule-free larva and postlarval stage i), higher expression in top region of sponge
SciCA3 Elevated expression in oocytes and early embryos; ubiquitous expression in other cell types including all larval cells. All stages, higher expression in sponges with oocytes and early embryos, larvae and postlarval stage i
SciCA4 Larval macromeres In larvae and postlarval stages ii-v, low expression in adult sponges
SciCA5 Undetected Higher in larvae, postlarval stages i-iii, young syconoid sponge, low in other stages and adult sponges
SciCA6 Undetected Very low expression during embryonic and postembryonic development
SciCA7 Proximal exopinacocytes between radial tubes Low expression in adult sponges
SciCA8 Undetected Low expression in adult sponges
SciCA9 (LCA) Undetected Highly expressed in postlarval-juvenile stages i-v, low expression otherwise
