Furin is a protease, a proteolytic enzyme activated by substrate presentation that in humans and other animals is encoded by the FURIN gene. Some proteins are inactive when they are first synthesized, and must have sections removed in order to become active.
The word "keel" comes from Old English cēol, Old Norse kjóll, = "ship" or "keel".It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work De Excidio et Conquestu Britanniae, under the spelling cyulae (he was referring to the three ships that the Saxons first arrived in).
On the beam; a relative bearing at right angles to the ship's keel; e.g. describing an object located at a bearing of 90 degrees or 270 degrees as measured clockwise from the ship's bow. [7] able seaman (AB) Also able-bodied seaman. A merchant seaman qualified to perform all routine duties on a vessel, or a junior rank in some navies.

A keel or carina (pl.: carinae) in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs. The keel provides an anchor to which a bird's wing muscles attach, thereby providing adequate leverage for flight.
The reinforced area of the deck surrounding the hole through which a mast passes as it rises from its step (usually on the keel) to the above-deck area [3] mast step The place in the hull where the lowest point of a mast rests, taking the weight of the mast and the thrust imposed by the tension of the rigging, and preventing lateral and fore ...
An alternate definition was provided in 2001, naming Carinatae an apomorphy-based clade defined by the presence of a keeled sternum. [2] The most primitive known bird relative with a keeled breastbone is Confuciusornis. While some specimens of this stem-bird have flat breastbones, some show a small ridge that could have supported a ...
Draft or draught (d) or (T) – The vertical distance from the bottom of the keel to the waterline. Used mainly to determine the minimum water depth for safe passage of a vessel and to calculate the vessel's displacement (obtained from ship's stability tables) so as to determine the mass of cargo on board.
