Predicted carboxy terminal membrane anchor.
Small stretch rich in Lysine, may be te ER retention signal?
Novel, with similarity to stretch of putative A. thaliana Myosin II heavy chain

TMpred Analysis:

Sequence: EFK...KNY, length: 98
Prediction parameters: TM-helix length between 17 and 33


1.) Possible transmembrane helices

The sequence positions in brackets denominate the core region.
Only scores above 500 are considered significant.

Inside to outside helices : 1 found
from to score center
75 ( 77) 95 ( 95) 2054 85

Outside to inside helices : 1 found
from to score center
76 ( 76) 94 ( 94) 2317 84




2.) Table of correspondences

Here is shown, which of the inside->outside helices correspond to which of the outside->inside helices.

Helices shown in brackets are considered insignificant.
A "+"-symbol indicates a preference of this orientation.
A "++"-symbol indicates a strong preference of this orientation.


inside->outside | outside->inside
75- 95 (21) 2054 | 76- 94 (19) 2317 ++




3.) Suggested models for transmembrane topology

These suggestions are purely speculative and should be used with extreme caution since they are based on the assumption that all transmembrane
helices have been found.
In most cases, the Correspondence Table shown above or the prediction plot that is also created should be used for the topology assignment of unknown
proteins.


2 possible models considered, only significant TM-segments used

-----> STRONGLY prefered model: N-terminus outside
1 strong transmembrane helices, total score : 2317
# from to length score orientation
1 76 94 (19) 2317 o-i

------> alternative model
1 strong transmembrane helices, total score : 2054
# from to length score orientation
1 75 95 (21) 2054 i-o
