Why did Roderick MacKinnon win the Nobel Prize?

Roderick MacKinnon surprised the whole research community when in 1998 he was able to determine the spatial structure of a potassium channel. Thanks to this contribution we can now “see” ions flowing through channels that can be opened and closed by different cellular signals.

Who discovered the potassium channel?

Roderick MacKinnon
But one particular question — how these electrical messengers manage to penetrate the normally impermeable cell membrane — occupied biochemistry laboratories for an entire century, until 1998, when Rockefeller University’s Roderick MacKinnon zeroed in on the answer by revealing the structure and mechanism of the cell’s …

What technology did MacKinnon use?

Recently, MacKinnon has begun delving into single-particle cryoelectron microscopy. This technique has allowed his lab to visualize the protein Slo2, a sodium-dependent potassium channel, which is activated under different sodium concentrations.

Who won the Chemistry Nobel Prize in 2003 and for what discoveries?

The Nobel Prize in Chemistry 2003 was awarded “for discoveries concerning channels in cell membranes” jointly with one half to Peter Agre “for the discovery of water channels” and with one half to Roderick MacKinnon “for structural and mechanistic studies of ion channels.”

Who amongst the following got a Nobel Prize in recognition of his discoveries of how salts and water transported in and out of cells in the human body?

Through pioneering discoveries concerning the water and ion channels of cells, this year’s Nobel Laureates Peter Agre and Roderick MacKinnon, have contributed to fundamental chemical knowledge on how cells function.

What did Carter get a Nobel Prize?

The Norwegian Nobel Committee has decided to award the Nobel Peace Prize for 2002 to Jimmy Carter, for his decades of untiring effort to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development.

What do potassium channel blockers do to the heart?

Potassium channel blockers result in QT prolongation that can set up for ventricular arrhythmias such as Torsades de Pointes or heart block. Continuous cardiac monitoring for arrhythmia disturbances is the mainstay of management for suspected potassium channel blocker overdose.
