General annotation (Comments)
| Function | Binds to actin filaments in muscle and non-muscle cells. Plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction. Smooth muscle contraction is regulated by interaction with caldesmon. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments. |
| Subunit structure | Heterodimer of an alpha and a beta chain. Binds to TMOD1. Ref.13 |
| Subcellular location | |
| Domain | The molecule is in a coiled coil structure that is formed by 2 polypeptide chains. The sequence exhibits a prominent seven-residues periodicity. |
| Involvement in disease | Nemaline myopathy 1 (NEM1) [MIM:609284]: A form of nemaline myopathy with autosomal dominant or recessive inheritance. Nemaline myopathies are muscular disorders characterized by muscle weakness of varying severity and onset, and abnormal thread-or rod-like structures in muscle fibers on histologic examination. Autosomal dominant nemaline myopathy type 1 is characterized by a moderate phenotype with onset between birth and early second decade of life. Weakness is diffuse and symmetric with slow progression often with need for a wheelchair in adulthood. The autosomal recessive form has onset at birth with moderate-to-severe hypotonia and diffuse weakness. In the most severe cases, death can occur before 2 years. Less severe cases have delayed major motor milestones, and these patients may walk, but often need a wheelchair before 10 years. Thyroid papillary carcinoma (TPC) [MIM:188550]: A common tumor of the thyroid that typically arises as an irregular, solid or cystic mass from otherwise normal thyroid tissue. Papillary carcinomas are malignant neoplasm characterized by the formation of numerous, irregular, finger-like projections of fibrous stroma that is covered with a surface layer of neoplastic epithelial cells. |

Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] Note: Additional isoforms seem to exist. | ||||||
| Isoform 1 (identifier: P06753-1) Also known as: Skeletal muscle; 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: P06753-2) Also known as: Cytoskeletal; TM30nm; The sequence of this isoform differs from the canonical sequence as follows: 1-80: MEAIKKKMQM...LELAEKKAAD → MAGITTIEAV...VEGERRAREQ 189-211: KCSELEEELKNVTNNLKSLEAQA → RCREMDEQIRLMDQNLKCLSAAE 259-284: ELYAQKLKYKAISEELDHALNDMTSI → KLKCTKEEHLCTQRMLDQTLLDLNEM | ||||||
| Note: Peptides 2-27, 41-55, 132-153, 163-169, 216-225 and 237-248 have been identified and sequenced by MS. Initiator Met-1 is removed. Contains a N-acetylalanine at position 2. Ref.8 (ABC40673) sequence corresponds to a TPM3 retrocopy (rcTPM3) on chromosome 16 that is generated by retroposition of reversed transcribed mRNA back to the genome. rcTPM3 functionality is uncertain. It has been detected by MS in primary breast cancer tissues. Contains a N6-acetyllysine at position 215. Contains a N6-acetyllysine at position 177. | ||||||
