5. MASTER REGULATOR OF CELLULAR AGING
DISCOVERED
TZAP IT’S A PROTEIN,
THAT BINDS THE ENDS
OF CHROMOSOMES
;DETERMINES HOW
LONG TELOMERES CAN
BE.
6. MASTER REGULATOR OF CELLULAR
AGING DISCOVERED
The researcher found that
TZAP controls a process
called telomere trimming,
ensuring that telomeres do
not become too long.
7. Others proteins like telomerase has
the same function as TZAP , but this
last protein does not develop
cancer.
MASTER REGULATOR OF CELLULAR AGING
DISCOVERED
8. This discovery was a surprise for many
scientists in the field believed there were
no additional proteins binding to
telomeres.
MASTER REGULATOR OF CELLULAR AGING
DISCOVERED
9. STUDENT OBSERVATION
This protein can be
clinically useful, because
besides of replicating the
sequenes of telomeric DNA
it does not produce cancer
10. Scientists discover a molecular motor has
a 'gear' for directional switching

11. SCIENTISTS DISCOVER A MOLECULAR MOTOR HAS A
'GEAR' FOR DIRECTIONAL SWITCHING
Motor proteins are molecular machines that
has an important function becouse this
protein converts chemical energy into
mechanical work,They are
considered"vehicles" of a cell
12. SCIENTISTS DISCOVER A MOLECULAR MOTOR
HAS A 'GEAR' FOR DIRECTIONAL SWITCHING
The function of many motor
proteins are still unclear, but
they know that motor proteins
shuttle cellular cargos between
locations and generate forces to
position chromosomes
13. SCIENTISTS DISCOVER A MOLECULAR MOTOR HAS A 'GEAR'
FOR DIRECTIONAL SWITCHING
For the discovery of a new motor
protein called KlpA, the
Researchers used a high-sensitivity light
microscopy method to directly follow
the movement of individual KlpA
molecules on the cytoskeleton track.
They discovered that KlpA is able to
move in opposite directions.Making the
difference between other motor
proteins that are undirectional.
14. STUDENT OBSERVATION
• This protein can be clinically useful, because
besides of replicating the sequences of
telomeric DNA it does not produce cancer
15. MEDICAL UTILITY
• The discovery of the proteins klpa and tzap,
even though their principal functions differ,
they still have great clinical importance.
17. MEDICAL UTILITY
• TZAP Allow how long telomeres can be, which
is very important because telomeres set the
lifespan of cells in the body, dictating critical
processes such as aging and the incidence of
cancer.
18. MEDICAL UTILITY
• KlpA-like motors proteins in humans are a
influation of cancer cell and eventually can
helps to lead to novel approaches to cancer
treatment.
