The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Pleckstrin-homology domain (PH domain)/Phosphotyrosine-binding domain (PTB)
".

FunFam 520: Muscle M-line assembly protein unc-89

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 5 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
Rho guanyl-nucleotide exchange factor activity GO:0005089
Stimulates the exchange of guanyl nucleotides associated with a GTPase of the Rho family. 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.
1 O01761 (/IDA)
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).
1 O01761 (/IPI)
Rho GTPase binding GO:0017048
Interacting selectively and non-covalently with Rho protein, any member of the Rho subfamily of the Ras superfamily of monomeric GTPases. Proteins in the Rho subfamily are involved in relaying signals from cell-surface receptors to the actin cytoskeleton.
1 O01761 (/IPI)
Phosphatase binding GO:0019902
Interacting selectively and non-covalently with any phosphatase.
1 O01761 (/IPI)
MATH domain binding GO:0090736
Interacting selectively and non-covalently with a meprin and TRAF homology (MATH) domain.
1 O01761 (/IPI)

There are 8 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
Positive regulation of gene expression GO:0010628
Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
1 O01761 (/IMP)
Skeletal muscle myosin thick filament assembly GO:0030241
The aggregation, arrangement and bonding together of proteins to form the myosin-based thick filaments of myofibrils in skeletal muscle.
1 O01761 (/IMP)
Myosin filament assembly GO:0031034
The aggregation, arrangement and bonding together of a filament composed of myosin molecules.
1 O01761 (/IMP)
Cellular protein localization GO:0034613
Any process in which a protein is transported to, and/or maintained in, a specific location at the level of a cell. Localization at the cellular level encompasses movement within the cell, from within the cell to the cell surface, or from one location to another at the surface of a cell.
1 O01761 (/IDA)
Positive regulation of locomotion GO:0040017
Any process that activates or increases the frequency, rate or extent of locomotion of a cell or organism.
1 O01761 (/IGI)
Positive regulation of striated muscle contraction GO:0045989
Any process that activates or increases the frequency, rate or extent of striated muscle contraction.
1 O01761 (/IGI)
Striated muscle myosin thick filament assembly GO:0071688
The aggregation, arrangement and bonding together of proteins to form the myosin-based thick filaments of myofibrils in striated muscle.
1 O01761 (/IMP)
Pharyngeal gland morphogenesis GO:1905905
The developmental process by which a pharyngeal gland is generated and organized.
1 O01761 (/IMP)

There are 2 GO terms relating to "cellular component"

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
M band GO:0031430
The midline of aligned thick filaments in a sarcomere; location of specific proteins that link thick filaments. Depending on muscle type the M band consists of different numbers of M lines.
1 O01761 (/IDA)
A band GO:0031672
The dark-staining region of a sarcomere, in which myosin thick filaments are present; the center is traversed by the paler H zone, which in turn contains the M line.
