General annotation (Comments)

Function

Involved in microtubule stabilization in many cell types, including neuronal cells. Specifically has microtubule cold stabilizing activity.

Subunit structure

Interacts with calmodulin (via C-terminus); the interaction is dependent on Ca2+ By similarity.

Subcellular location

Cytoplasm › cytoskeleton. Golgi apparatus By similarity. Note: Colocalizes with neurofilament (NF)-rich inclusions in spinal chord and brain neurons of patients with amyotrophic lateral sclerosis (ALS). Ref.3

Tissue specificity

Expressed in brain (at protein level). Expressed in spinal chord. Isoform 2 expression is up-regulated in the prefrontal cortex (Brodmann's area 46) of patients with schizophrenia (postmortem brain study). Ref.3 Ref.4

Sequence similarities

Belongs to the STOP family.

Sequence caution

The sequence AAH63860.1 differs from that shown. Reason: Erroneous initiation.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q96JE9-1)

Also known as: N-STOP; Neuronal-STOP;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q96JE9-2)

Also known as: E-STOP; Early-STOP;

The sequence of this isoform differs from the canonical sequence as follows:
     440-813: Missing.
