The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:

"
Son of sevenless (SoS) protein Chain: S domain 1

FunFam 21: Low temperature essential protein

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 2 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Ras guanyl-nucleotide exchange factor activity GO:0005088
Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Ras superfamily. Under normal cellular physiological conditions, the concentration of GTP is higher than that of GDP, favoring the replacement of GDP by GTP in association with the GTPase.

Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
4 P07866 (/IPI) P07866 (/IPI) P07866 (/IPI) P07866 (/IPI)

There are 4 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Vesicle-mediated transport GO:0016192
A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.
4 P07866 (/IGI) P07866 (/IGI) P07866 (/IGI) P07866 (/IGI)
Positive regulation of exit from mitosis GO:0031536
Any process that activates or increases the rate of progression from anaphase/telophase (high mitotic CDK activity) to G1 (low mitotic CDK activity).
4 P07866 (/IMP) P07866 (/IMP) P07866 (/IMP) P07866 (/IMP)
Mitotic spindle orientation checkpoint GO:0031578
A cell cycle checkpoint that monitors and signals errors in the placement or orientation of the spindle in the cell. This delays the completion of anaphase until errors are corrected.
4 P07866 (/TAS) P07866 (/TAS) P07866 (/TAS) P07866 (/TAS)
Asymmetric protein localization to new mitotic spindle pole body GO:0061510
Any process in which a protein is transported to, or maintained to the new mitotic spindle pole body resulting in its being distributed asymmetrically.

GO Term Annotations Evidence
Cellular bud GO:0005933
A protuberance from a cell of an organism that reproduces by budding, which will grow larger and become a separate daughter cell after nuclear division, cytokinesis, and cell wall formation (when appropriate). The daughter cell may completely separate from the mother cell, or the mother and daughter cells may remain associated.
